'Sanctify Them' in the Bible

And they began to sanctify themselves on the first day of the first month. And on the eighth day of the month they came to the portico of Yahweh. And they sanctified the house of Yahweh for eight days, and on the sixteenth day of the first month they finished.

But the priests were too few, and they were not able to offer all the burnt offerings, so their brothers, the Levites, strengthened them to finish the work, and until the [rest of] the priests consecrated themselves. (For the Levites [were] {more conscientious} to sanctify themselves than the priests.)
