'Consecrate' in the Bible

The priest shall offer the one as a sin offering and the other as a burnt offering and make atonement for him concerning his sin because of the [dead] body. He shall consecrate his head the same day,

and he shall dedicate himself to the Lord for the time of his separation and shall bring a male lamb a year old as a guilt offering; but the previous days will be void and lost, because his separation was defiled.

Say to the people, ‘Consecrate (separate as holy) yourselves for tomorrow, and you shall eat meat; for you have wept [in self-pity] in the ears of the Lord, saying, “Who will give us meat to eat? For we were well-off in Egypt.” Therefore the Lord will give you meat, and you shall eat.
