(19) Tarry ye also here this night.--Balaam knew that God was "not a man, that he should lie; neither the son of man, that he should repent" (Numbers 23:19); and yet he indulged the vain expectation that he might be allowed to curse those whom God had declared to be blessed.

22:15-21 A second embassy was sent to Balaam. It were well for us, if we were as earnest and constant in prosecuting a good work, notwithstanding disappointments. Balak laid a bait, not only for Balaam's covetousness, but for his pride and ambition. How earnestly should we beg of God daily to mortify such desires in us! Thus sinners stick at no pains, spare no cost, and care not how low they stoop, to gratify their luxury, or their malice. Shall we then be unwilling to do what is right? God forbid! Balaam's convictions charged him to keep to the command of God; nor could any man have spoken better. But many call God theirs, who are not his, not truly because not only his. There is no judging men by their words; God knows the heart. Balaam's corruptions at the same time inclined him to go contrary to the command. He seemed to refuse the temptation; but he expressed no abhorrence of it. He had a strong desire to accept the offer, and hoped that God might give him leave to go. He had already been told what the will of God was. It is a certain evidence of the ruling of corruption in the heart, to beg leave to sin. God gave Balaam up to his own heart's lusts. As God sometimes denies the prayers of his people in love, so sometimes he grants the desires of the wicked in wrath.Now therefore, I pray you, tarry ye also here this night,.... As the former messengers had; this shows his strong inclination to go along with them, and do what was desired of him, could he be permitted; otherwise he might and ought to have told the messengers at once that Balak needed not to have given himself and them so much trouble, since it was not in his power to do for him what he requested; nor would he attempt it, as being contrary to the will of God, and therefore it would be their best way to return as soon as they could; but instead of that, he desires them to stay that night, which must give them some hope of succeeding in their embassy:

that I may know what the Lord will say unto me more; he hoped he would change his mind, and say something to him different from, and contrary to what he had before declared unto him, which to suppose of God is great vileness and wickedness; to such a pitch did his greedy desire after riches and honour work him up into; he ought to have been satisfied with the answer already given him, and not to have inquired more.
