Nehemiah 13:29

Remember them. — This priestly violation of law is committed to God alone for punishment.

And of the Levites. — God chose the tribe of Levi for Himself, specially the house of Aaron, and every priest was to be “holy to the Lord” (Leviticus 21:6; Leviticus 21:8). This was “the covenant of the priesthood;” though there may be an undertone of reference to the great covenant in Nehemiah 10.
