'Sanctify' in the Bible

and said unto them, Hear me, ye Levites; now sanctify yourselves, and sanctify the house of Jehovah, the God of your fathers, and carry forth the filthiness out of the holy place.

Now they began on the first day of the first month to sanctify, and on the eighth day of the month came they to the porch of Jehovah; and they sanctified the house of Jehovah in eight days: and on the sixteenth day of the first month they made an end.

But the priests were too few, so that they could not flay all the burnt-offerings: wherefore their brethren the Levites did help them, till the work was ended, and until the priests had sanctified themselves; for the Levites were more upright in heart to sanctify themselves than the priests.

For there were many in the assembly that had not sanctified themselves: therefore the Levites had the charge of killing the passovers for every one that was not clean, to sanctify them unto Jehovah.

And kill the passover, and sanctify yourselves, and prepare for your brethren, to do according to the word of Jehovah by Moses.
