'Consecrate Yourselves' in the Bible

For I am the Lord your God; so consecrate yourselves and be holy, for I am holy. You shall not make yourselves unclean with any of the swarming things that swarm or crawls on the ground.

You shall consecrate yourselves therefore, and be holy; for I am the Lord your God.

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.

And he said, “In peace; I have come to sacrifice to the Lord. Consecrate yourselves and come with me to the sacrifice.” He also consecrated Jesse and his sons and invited them to the sacrifice.
