Leviticus 11-16 are about how to discern “cleanliness” vs. “uncleanliness.” God is giving us these instructions because He is holy — literally, set apart or distinct — and wants us to be holy, i.e., set apart for God’s purpose. God does not say that we will never be in a situation where we will be exposed to “uncleanliness.” Exposure to “uncleanliness” is a part of being in this world. God is giving us a simple object lesson about how to go from unclean to clean, from unholy to holy.
Uncleanness is not a sin in and of itself. It’s a temporary state, not a permanent state. God shows here how to go from unclean to clean, not only of ourselves but of household items, clothing, etc. God is showing us how clean He is and how we are to become like him. This isn’t about “dos and don’ts” but because He wants us to be holy and to be His people.
We pause before studying Yeshua’s Passover meal with the 12 to consider an account (Mt. 26:1–16; Mk. 14:1–11; Jn. 12:1–11; Lk. 7:36–50) so important that Yeshua said it must be recounted wherever the good news of the Kingdom of God and the role of God’s Mashiakh (Messiah) in healing the gulf between mankind and God is proclaimed.
