Numbers 23:1 - Joseph Benson’s Commentary on the Old and New Testaments

Build me seven altars To the true God, otherwise he would not have mentioned it to God as an argument why he should grant his requests, as he does, Numbers 23:4. And though Balak was averse from God and his worship, yet he would be easily overruled by Balaam, who doubtless told him that it was in vain to make an address to any other than the God of Israel, who alone was able either to bless or curse them, as he pleased. Seven This being the usual number in the more solemn and important sacrifices, even among those worshippers of the true God who were not of the seed of Abraham, nor favoured with a written revelation, Job 42:8. Perhaps it was intended to show that they worshipped Him who had in a manner consecrated the number seven, by ceasing from his works of creation on the seventh day. It may not be improper to notice here how much the number seven is regarded in the sacred writings. The blood of atonement was to be sprinkled seven times before the mercy-seat, Leviticus 16:14; the consecrating oil was to be sprinkled seven times upon the altar, Leviticus 8:11; the leper was to be sprinkled seven times, and seven days were appointed for his cleansing, Leviticus 14:7-9; seven days were to be employed in consecrating the priests, (Leviticus 8:35,) and for purifying the unclean, Leviticus 12:2; Numbers 19:19; seven times Naaman washed in Jordan, 2 Kings 5:10; 2 Kings 5:14; seven days Jericho was besieged, and seven priests with seven trumpets blew, and the walls fell down, Joshua 6.; seven priests blew trumpets before the ark when David brought it home, 1 Chronicles 15:24; every seventh day was a sabbath; the seventh year a year of rest; and seven times seven years brought the jubilee. The principal events that should befall the world and the church, from the time of the banishment of St. John to the isle of Patmos, in the reign of Domitian, (A.D. 96,) to the consummation of all things, are comprehended in that wonderful book of prophecy termed the Revelation, by St. John, under the emblems of seven seals of a book opened, seven trumpets sounded by seven angels, and seven vials poured out also by seven angels. Now what more solid reason can be assigned for this peculiar regard shown by God himself to the number seven, than that it was intended to hold him forth to mankind as that Jehovah who had created the world in six days, and by resting on the seventh, had consecrated that number, and rendered it in some sense sacred to all nations and ages?
