Nehemiah 13:28-30

28 One of the sons of Joiada was the son-in-law of Sanballat. Joiada was the high priest. He was the son of Eliashib. I drove Joiada's son away from me. Sanballat was a Horonite.

29 You are my God. Remember what those priests have done. They have polluted their own work. They have also polluted the covenant that God made with the priests and Levites long ago.

30 So I made the priests and Levites pure. I made them pure from every practice that had come from other countries and had polluted them. I gave them their duties. Each one had his own job to do.
