Nehemiah 13:28-30

28 One of the sons of Joiada, son of Eliashib the high priest, was the son-in-law of Sanballat the Horonite! I drove him from my presence.

29 Remember against them, O my God, how they defiled the priesthood and the covenant of the priesthood and the Levites!

30 Thus I cleansed them of all foreign contamination. I established the various functions for the priests and Levites, so that each had his appointed task.
