Seven shows up repeatedly in Scripture. It appears first with the seventh day of creation, threads through God’s cycles of appointments with mankind, and foreshadows the timing of Messiah Yeshua’s arrival as the Word become flesh and culminates with many of the symbols of the Day of the Lord.
Last week, we read Moses told the people over and over that they were to destroy all the places where the people of the land worshipped their gods. He told the people that after they destroy all the places the people of the land worship their gods, they were to be thoughtful about what place they use to make their offerings and kill their food animals. In the rest of chapter 12, Moses told Israel there will come a time when there will be only one place where the people will be allowed to present sacrificial animals to the Lord.
God was giving Israel the Land to posses it, but He wouldn’t go in until they clean it up of the wicked pagan influences, starting with the false-worship places.
Moses specially addressed the adults of the community who are preparing to enter the Promised Land to teach their children God’s charge, commandments, judgements and statutes. There are two parts to sanctification: mind and heart. Once the mind is sanctified, the heart will follow. Once the mind and heart are sanctified, the person will not depart from God.
Instructions on the shvi’it (“seventh”), the year of shmitah (“release”) or sabbatical year, are part of a larger teaching in Deuteronomy 14–16 on the Fourth Commandment, to guard the seventh day of the week as a holy memorial. But these instructions on care for the poor and releasing debts during the shmitah show us how the various Shabbat memorials remind us of all God has released us from through Yeshua haMashiakh (Jesus the Christ).
These instructions of “clean” and “unclean” animals connect to a bigger lesson in Deuteronomy 13–14 on the Third Commandment, about blaspheming the Name of the LORD, or making the Name common. “Cleaning” what’s distant from God is the real lesson beyond clean/unclean in Leviticus 11, Deuteronomy 14 and Acts 10.
