Jamieson, Fausset and Brown on Numbers 23:1

CHAPTER 23

Nu 23:1-30. Balak's Sacrifices.

1. Balaam said unto Balak, Build me here seven altars--Balak, being a heathen, would naturally suppose these altars were erected in honor of Baal, the patron deity of his country. It is evident, from Nu 23:4 that they were prepared for the worship of the true God; although in choosing the high places of Baal as their site and rearing a number of altars (2Ki 18:22; Is 17:8; Jr 11:13; Ho 8:11; 10:1), instead of one only, as God had appointed, Balaam blended his own superstitions with the divine worship. The heathen, both in ancient and modern times, attached a mysterious virtue to the number seven; and Balaam, in ordering the preparation of so many altars, designed to mystify and delude the king.
