And he said unto them, ye are the chief of the fathers of the Levites,.... Of the families of the Levites, heads of their fathers' houses:
sanctify yourselves, both ye and your brethren; respectively under each, whose numbers are before given, by washing their bodies and clothes, and abstaining from their wives:
that you may bring up the ark of the Lord God of Israel unto the place that I have prepared for it; 2 Samuel 6:17.
