And Balaam said unto Balak, Build me here seven altars, and prepare me here seven oxen and seven rams.

Wesley's Notes

23:1 Build 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 doth, Nu 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 solemn and usual number in sacrifices.

Jamieson-Fausset-Brown Bible Commentary

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; Isa 17:8; Jer 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.

Matthew Henry's Concise Commentary

23:1-10 With the camps of Israel full in view, Balaam ordered seven altars to be built, and a bullock and a ram to be offered on each. Oh the sottishness of superstition, to imagine that God will be at man's beck! The curse is turned into a blessing, by the overruling power of God, in love to Israel. God designed to serve his own glory by Balaam, and therefore met him. If God put a word into the mouth of Balaam, who would have defied God and Israel, surely he will not be wanting to those who desire to glorify God, and to edify his people; it shall be given what they should speak. He who opened the mouth of the ass, caused the mouth of this wicked man to speak words as contrary to the desire of his heart, as those of the ass were to the powers of the brute. The miracle was as great in the one case as in the other. Balaam pronounces Israel safe. He owns he could do no more than God suffered him to do. He pronounces them happy in their distinction from the rest of the nations. Happy in their numbers, which made them both honourable and formidable. Happy in their last end. Death is the end of all men; even the righteous must die, and it is good for us to think of this with regard to ourselves, as Balaam does here, speaking of his own death. He pronounces the righteous truly blessed, not only while they live, but when they die; which makes their death even more desirable than life itself. But there are many who desire to die the death of the righteous, but do not endeavour to live the life of the righteous; gladly would they have an end like theirs, but not a way like theirs. They would be saints in heaven, but not saints on earth. This saying of Balaam's is only a wish, not a prayer; it is a vain wish, being only a wish for the end, without any care for the means. Many seek to quiet their consciences with the promise of future amendment, or take up with some false hope, while they neglect the only way of salvation, by which a sinner can be righteous before God.
