(a) For among the Gentiles the kings often used to sacrifice, as did the priests.
And Balak did as Balaam had spoken,.... Ordered seven altars to be built, and prepared seven bullocks and rams for sacrifice:
and Balak and Balsam offered on every altar a bullock and a ram; both seem to be concerned in offering the sacrifices; Balak, though a king, it being usual for kings to be priests also, as Melchizedek was, and Balaam as a prophet; and these sacrifices were offered to the true God, as seems clear from Numbers 23:4 and to which Balak, at the direction of Balaam, agreed, in order to gain the Lord on his side, that he might prevail over the people of Israel.
