(3.) To be very constant (v. 8): Cleave unto the Lord your God, that is, "delight in him, depend upon him, devote yourselves to his glory, and continue to do so to the end, as you have done unto this day, ever since you came to Canaan;" for, being willing to make the best of them, he looks not so far back as the iniquity of Peor. There might be many things amiss among them, but they had not forsaken the Lord their God, and it is in order to insinuate his exhortation to perseverance with the more pleasing power that he praises them. "Go on and prosper, for the Lord is with you while you are with him." Those that command should commend; the way to make people better is to make the best of them. "You have cleaved to the Lord unto this day, therefore go on to do so, else you lose the praise and recompence of what you have wrought. Your righteousness will not be mentioned unto you if you turn from it."
