'Consecrate' in the Bible

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.

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.”
