'Consecrate' in the Bible

Have ye not cast out the priests of the LORD, the sons of Aaron, and the Levites, and have made you priests after the manner of the nations of other lands? so that whosoever cometh to consecrate himself with a young bullock and seven rams, the same may be a priest of them that are no gods.

He said to them, “Hear me, Levites. Consecrate yourselves now and consecrate the temple of Yahweh, the God of your ancestors. Remove everything impure from the holy place.

"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.

However, since there were not enough priests, they weren’t able to skin all the burnt offerings, so their Levite brothers helped them until the work was finished and until the priests consecrated themselves. For the Levites were more conscientious to consecrate themselves than the priests were.

for there were many in the assembly who had not consecrated themselves, and so the Levites were in charge of slaughtering the Passover lambs for every unclean person to consecrate the lambs to the Lord.

Slaughter the Passover lambs, consecrate yourselves, and make preparations for your brothers to carry out the word of the Lord through Moses.”
