'Consecrate' in the Bible

"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.

They began their consecration duties on the first day of the first month and finished at the LORD's outer vestibule on the eighth day of the month. Another eight days was used to consecrate the LORD's Temple, so they completed the work on the sixteenth day of the first month.

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