7 Thus you shall do to them to cleanse them: sprinkle the ^zwater of purification upon them, and let them ^ago with a razor over all their body, and wash their clothes and cleanse themselves.

20 For the priests and the Levites had ^lpurified themselves together; all of them were clean. So ^mthey slaughtered the Passover lamb for all the returned exiles, for their fellow priests, and for themselves.

30 And the priests and the Levites ^vpurified themselves, and they purified the people and the gates and the wall.

22 Then I commanded the Levites that they should purify themselves and come and guard the gates, to keep the Sabbath day holy. Remember this also in my favor, O my God, and spare me according to the greatness of your steadfast love.
