What is the Shabbat (Sabbath)?

Shabbat (שבת), called Sabbath in English, is a weekly appointment with God, coming each seventh day.

It is a multilayered memorial of key characteristics of the Holy One:

• God is the Creator of the heavens and the earth (Gen. 2:2–3; Ex. 20:8–11).
• God is the Sanctifier, the One Who makes people holy by setting them apart to be Heaven’s ambassadors on earth (Ex. 31:13–15; 19:6).
• God is Provider of our “daily bread” (Ex. 16:22–30; Mt. 6:11; Lk. 11:3).
• God is Liberator from slavery and obstructions between Heaven and mankind (Dt. 5:12–15).
• The Messiah is healer of body and “heart” connection to God (Mt. 12:9–14).
• The Kingdom of God, symbolized also by the Promised Land, will provide the world with “rest” from the misery of being ruled by the Kingdom of the Adversary (Psalm 95:7–11; Hebrews 3–4).
  • The Messiah is ultimate high priest of Israel, “shabbating” the separation between mankind and God (Mt. 11:28–30; 2Cor. 5:14–19; Eph. 2:11–22).
• Shabbat and Rosh Chodesh (New Moon) will be weekly and monthly memorials, respectively, even after God recreates the heavens and Earth (Isa. 66:22–23; Rev. 21:1–4; 2Peter 3:10–13).

How are the words for ‘sabbath’ handled in the New Testament?

The Greek forms are easy to confuse in transliteration:

• σάββατον sábbaton is nominative or accusative singular: “Sabbath.”
• σάββατα sábbata is nominative or accusative plural: “Sabbaths.”
• σαββάτων sabbátōn — often written simply sabbaton without the macron — is genitive plural: “of Sabbaths,” but idiomatically sometimes “of the week.”

All belong to the same neuter noun, σάββατον, σαββάτου, τό. It entered Greek from Hebrew שַׁבָּת Shabbat, probably through Aramaic. The noun appears approximately 68 times in printed Greek New Testaments if Mark 16:9 is included, or 67 if the disputed longer ending of Mark is excluded, according to the MorphGNT–SBLGNT database, based on Michael Holmes’s critical SBL Greek New Testament.

Greek form	Parsing	Approximate occurrences	Normal English rendering
σάββατον sabbaton	Nominative/accusative singular	14	Sabbath
σαββάτου sabbatou	Genitive singular	13	of the Sabbath; of the week
σαββάτῳ sabbatō	Dative singular	16	on the Sabbath
σάββατα sabbata	Nominative/accusative plural	1	Sabbaths
σαββάτων sabbatōn	Genitive plural	11	of the Sabbath(s); of the week
σάββασιν sabbasin	Dative plural	13	on the Sabbath; on Sabbaths

The striking feature is that grammatical number does not always equal semantic number. A plural Greek form can denote one Sabbath, while both singular and plural genitives can designate a seven-day week. Standard lexicons therefore give σάββατον sabbaton the meanings “Sabbath day” and, in certain constructions, “week.” The University of Chicago’s Logeion aggregates the major scholarly Greek lexicons and identifies its basic meaning as the Hebrew Sabbath.

Singular forms normally mean “Sabbath”

The unambiguous singular sabbaton frequently names the seventh-day Sabbath:

• “The Sabbath was made for man” — τὸ σάββατον (Mark 2:27).
• “The Son of Man is Lord even of the Sabbath” — τοῦ σαββάτου (Matt. 12:8; Mark 2:28; Luke 6:5).
• “The Sabbath was about to begin” — σάββατον (Luke 23:54).
• “They rested on the Sabbath” — τὸ σάββατον (Luke 23:56).
• “That day was a Sabbath” — σάββατον (John 5:9; 9:14).
• “Moses is read every Sabbath” — πᾶν σάββατον (Acts 15:21).
• Paul reasoned in the synagogue “every Sabbath” — πᾶν σάββατον (Acts 18:4).

The singular dative σαββάτῳ likewise normally means “on the Sabbath”:

• Matthew 12:2; 24:20
• Luke 6:1, 6–7, 9; 13:14–15; 14:1, 3
• Acts 13:44
• John 5:16; 7:22–23; 19:31

Therefore, when no calendrical numeral or idiomatic expression intervenes, “Sabbath” is overwhelmingly the proper translation.

A plural form can refer to one Sabbath

Jewish Greek often used the plural forms σάββατα, sabbátōn and σάββασιν for a single Sabbath day. This is not a translation error. It is an established idiom found in the Septuagint, Josephus and the Apostolic Writings.

For example:

• Matthew 12:1 uses τοῖς σάββασιν, grammatically “on the Sabbaths,” for the Sabbath on which the disciples plucked grain.
• The next verse switches to the singular σαββάτῳ without changing the day or subject (Matt. 12:2).
• Mark 2:23–24 uses the plural σάββασιν for the same singular Sabbath incident.
• Luke reverses the pattern: the narrative begins with singular σαββάτῳ in Luke 6:1 and switches to plural σάββασιν in 6:2.
• Matthew 12:10–12 and Mark 3:2–4 use plural forms for a particular Sabbath, while the parallel in Luke 6:6–9 uses singular forms.
• Luke 4:16 says Yeshua entered the synagogue “on the day of the Sabbaths,” ἐν τῇ ἡμέρᾳ τῶν σαββάτων, meaning “on the Sabbath day.”
• Acts 13:14 and 16:13 similarly use ἡμέρᾳ τῶν σαββάτων for one Sabbath day.

This interchangeable singular-plural usage is also found in the LXX, where a singular Hebrew שַׁבָּת Shabbat may be translated by either singular σάββατον or plural σάββατα. Scholarly analysis notes that plural festival names were common in Jewish and wider Hellenistic Greek. Similar plurals could name one celebration rather than several separate celebrations. The detailed linguistic survey in The Sabbath in Scripture and History observes that the Gospel parallels alternate between singular and plural forms “without any discernable difference of meaning.” (Academic text)

Therefore, the rule “plural Greek must mean multiple Sabbaths” does not work in Jewish Koine Greek.

Only one occurrence of sabbata unmistakably means multiple Sabbaths

The exact nominative/accusative plural σάββατα sabbata occurs only in Acts 17:2:

ἐπὶ σάββατα τρία
epi sabbata tria
“for three Sabbaths”

The numeral τρία tria requires more than one Sabbath. Paul reasoned from the Scriptures on three successive Sabbath days.

Translations handle the expression in two ways:

• “for three Sabbaths” — NASB, ESV and several formal translations.
• “for three weeks” — RSV and some dynamically equivalent translations.

“Three Sabbaths” preserves the lexical wording. “Three weeks” expresses the elapsed weekly sequence: three successive Sabbaths cover a period of three weeks. Thus, “weeks” is contextually reasonable, but it is a metonymic translation rather than the most direct lexical equivalent.

Acts 17:2 does not demonstrate that sabbata normally means “weeks.” It demonstrates that repeated Sabbaths can mark repeated weekly intervals.

“Sabbath” can designate an entire week

The semantic development is straightforward. Because each seven-day period ended in a Sabbath, “Sabbath” could function metonymically for the period bounded or identified by that Sabbath.

Dieter Georgi notes that even Paul’s predominantly non-Jewish Corinthian audience reckoned the week “in a Jewish fashion from its last day, the sabbath.” Thus, 1Corinthians 16:2 uses sabbaton rather than the ordinary Greek ἑβδομάς hebdomas for “week.” (Harvard Theological Review)

Significantly, the standard Greek word ἑβδομάς hebdomas, “a period of seven; week,” appears in the LXX and other Greek literature but not in the New Testament. The Apostolic writers instead preserve Jewish calendrical speech centered upon Shabbat.

Two singular-genitive examples clearly mean “week”:

Luke 18:12

νηστεύω δὶς τοῦ σαββάτου
nēsteuō dis tou sabbatou
“I fast twice a week”

The Pharisee did not mean that he fasted twice during one Sabbath day. The genitive singular σαββάτου designates the recurring seven-day period.

1Corinthians 16:2

κατὰ μίαν σαββάτου
kata mian sabbatou
“on every first day of the week”

Here μίαν mian is feminine because an unstated feminine noun, ἡμέραν hēmeran (“day”), is understood: “on every first [day] of the week.”

Mark 16:9

In manuscripts containing the longer ending, uses the same singular construction:

πρωῒ πρώτῃ σαββάτου
prōi prōtē sabbatou
“early on the first day of the week”

Thus, singular σαββάτου can mean either “of the Sabbath” or “of the week.” Syntax and context decide which sense is intended.

The plural sabbátōn can also mean “week”

Six undisputed occurrences of genitive plural σαββάτων sabbátōn appear in expressions conventionally translated “the first day of the week”:

Passage	Greek expression	Conventional translation
Matthew 28:1b	εἰς μίαν σαββάτων	toward the first day of the week
Mark 16:2	τῇ μιᾷ τῶν σαββάτων	on the first day of the week
Luke 24:1	τῇ δὲ μιᾷ τῶν σαββάτων	on the first day of the week
John 20:1	τῇ δὲ μιᾷ τῶν σαββάτων	on the first day of the week
John 20:19	τῇ μιᾷ σαββάτων	on the first day of the week
Acts 20:7	ἐν δὲ τῇ μιᾷ τῶν σαββάτων	on the first day of the week

With Mark 16:9 and 1Corinthians 16:2 using the singular genitive, these constitute the familiar eight “first day of the week” passages.

The feminine μιᾷ mia is important. Σάββατον Sabbaton is neuter, so μιᾷ does not grammatically modify σαββάτων. It agrees with an implied feminine ἡμέρᾳ hēmera, “day”:

τῇ μιᾷ [ἡμέρᾳ] τῶν σαββάτων
“on the first [day] of the week”

Μία normally means “one,” but Semitic calendrical usage employs “day one” for the first day, as in Genesis 1:5. English therefore translates the idiom naturally as “the first day of the week.”

The “first day of the week” construction predates the Apostolic Writings

The construction is not an invention of later Christian translators. Comparable Jewish Greek occurs in the Septuagint’s Psalm titles:

• Psalm 23:1 LXX: τῆς μιᾶς σαββάτων, “for the first day of the week.”
• Psalm 47:1 LXX: δευτέρᾳ σαββάτου, “for the second day of the week.”
• Psalm 93:1 LXX: τετράδι σαββάτων, “for the fourth day of the week.”

These titles identify particular days in the Temple’s weekly psalm cycle. The ordinal or numerical expression identifies a day by its relationship to Shabbat.

Matthew Black accordingly classifies μία τῶν σαββάτων as a Semitic calendrical expression in An Aramaic Approach to the Gospels and Acts, 3rd ed., p. 90. C.F.D. Moule’s An Idiom Book of New Testament Greek likewise treats such constructions within the Semitic character of New Testament Greek. These are grammatical and linguistic judgments, not theological conclusions about later Sunday observance.

Therefore, translating μία τῶν σαββάτων as “the first day of the week” is linguistically well grounded. A wooden rendering such as “one of the Sabbaths” reproduces individual Greek glosses but fails to communicate the established Jewish Greek idiom.

Not every sabbatown means “week”

The genitive plural σαββάτων sabbátōn has three different contextual functions.

It can mean one Sabbath

• Matthew 28:1a: ὀψὲ δὲ σαββάτων, “after the Sabbath” or possibly “late on the Sabbath.”
• Luke 4:16: ἐν τῇ ἡμέρᾳ τῶν σαββάτων, “on the Sabbath day.”
• Acts 13:14: τῇ ἡμέρᾳ τῶν σαββάτων, “on the Sabbath day.”
• Acts 16:13: τῇ ἡμέρᾳ τῶν σαββάτων, “on the Sabbath day.”

It can mean “week” in a numbered-day construction

• Matthew 28:1b
• Mark 16:2
• Luke 24:1
• John 20:1, 19
• Acts 20:7

It can denote Sabbaths as a category

• Colossians 2:16: μέρει ἑορτῆς ἢ νουμηνίας ἢ σαββάτων, “in regard to a festival, new moon or Sabbath(s).”

In Colossians 2:16, there is no numeral and no implied “first day.” Consequently, “week” is not an appropriate translation. Σαββάτων refers to Sabbath observance, whether rendered collectively as “a Sabbath day,” generically as “Sabbath,” or formally as “Sabbaths.”

The sequence “festival–new moon–Sabbath” corresponds to the annual–monthly–weekly calendrical formula found in 1Chronicles 23:31; 2Chronicles 2:4; 8:13; 31:3; Nehemiah 10:33; Ezekiel 45:17 and Hosea 2:11. Accordingly, many scholars understand σαββάτων in Colossians 2:16 as the weekly Sabbath viewed generically, not specifically as annual festival Sabbaths.

How “Sabbath,” “week” and “weeks” compare

Translation	When justified	Representative passages
Sabbath	The seventh day, whether the Greek form is singular or idiomatically plural	Matt. 12:1–12; Mark 2:23–28; Luke 4:16; Acts 13:14
Sabbaths	Multiple Sabbath days are explicitly intended, or Sabbaths are treated collectively	Acts 17:2; possibly Col. 2:16
Week	The seven-day period is intended, especially with a numbered day or frequency expression	Luke 18:12; Matt. 28:1b; Mark 16:2, 9; Luke 24:1; John 20:1, 19; Acts 20:7; 1Cor. 16:2
Weeks	A translation of the time span created by multiple successive Sabbaths	Acts 17:2 in the RSV and similar renderings

The raw form alone therefore cannot determine the English translation:

• Singular σαββάτου may mean “of the Sabbath” or “of the week.”
• Plural σαββάτων may mean “of the Sabbath,” “of the Sabbaths” or “of the week.”
• Plural σάββασιν commonly refers to one Sabbath.
• Plural σάββατα in Acts 17:2 genuinely refers to three separate Sabbaths.

The controlling factors are syntax, numerals, idiom, literary context and established Jewish Greek usage.

Conclusion

In the Apostolic Writings, sabbaton fundamentally denotes Shabbat, but it developed two related extensions. First, plural forms can designate a single Sabbath without a meaningful difference from the singular. Second, because the Jewish week was reckoned in relation to Shabbat, singular or plural genitives can denote the seven-day week, particularly in expressions such as “first day of the week” and “twice a week.”

Therefore, “Sabbath” is the dominant meaning; “week” is a well-established contextual meaning; and “weeks” is usually a dynamic translation of repeated Sabbaths rather than the basic lexical meaning of σάββατα. Most importantly, grammatical plurality by itself does not prove that a passage concerns several Sabbaths, annual Sabbaths or the seven Sabbaths counted toward Shavuot. The entire construction must decide the sense.
