'Consecrate Yourselves' in the Bible

"But give this command to the people: "You are to consecrate yourselves, because tomorrow you're going to eat meat, since you've complained where the LORD can hear it, "Who can give us meat to eat? After all, life was better with us in Egypt." Therefore, the LORD is going to give you meat and you'll eat

Then Joshua addressed the people: "Consecrate yourselves, because tomorrow the LORD will do marvelous things among you."

He said, "Peace, I've come to sacrifice to the LORD. Consecrate yourselves and come with me to the sacrifice." Samuel consecrated Jesse and his sons and invited them to the sacrifice.

"Pay attention to me, you descendants of Levi! Consecrate yourselves and the Temple of the LORD God of your ancestors by taking out from the Holy Place whatever is unclean. Our ancestors have been unfaithful. They practiced what the LORD considers to be evil, abandoned him, turned their faces away from the place where the LORD resides, and turned their backs to him.

Now slaughter the Passover, consecrate yourselves, and prepare your relatives to obey the command from the LORD given by Moses."
