'Consecrate' in the Bible

But you banished the Lord's priests, Aaron's descendants, and the Levites, and appointed your own priests just as the surrounding nations do! Anyone who comes to consecrate himself with a young bull or seven rams becomes a priest of these fake gods!

He said to them: "Listen to me, you Levites! Now consecrate yourselves, so you can consecrate the temple of the Lord God of your ancestors! Remove from the sanctuary what is ceremonially unclean!

But there were not enough priests to skin all the animals, so their brothers, the Levites, helped them until the work was finished and the priests could consecrate themselves. (The Levites had been more conscientious about consecrating themselves than the priests.)

Because many in the assembly had not consecrated themselves, the Levites slaughtered the Passover lambs of all who were ceremonially unclean and could not consecrate their sacrifice to the Lord.

Slaughter the Passover lambs, consecrate yourselves, and make preparations for your countrymen to do what the Lord commanded through Moses."
