2 Samuel 10:19

The kings that were servants to Hadarezer He being the most powerful prince in those parts, it appears there were several petty kings that were subject to him. They made peace with Israel, and served them As it is likely Hadarezer himself also did: whereby God fulfilled his promise to Abraham, (which was renewed to Joshua,) of enlarging the dominion of his posterity as far as Euphrates. See Genesis 15:18; Joshua 1:2. Wonderful to reflect on! kingdoms and vast tracts of country, which were promised by God, ages before, to the posterity of a man who had not one foot of property in them, we see here all falling, with a very particular exactness, under the dominion of one of the posterity of him to whom they had been promised! So faithful is God, and all his purposes will be fulfilled! Thus, in the space of nineteen or twenty years, David had the happiness of finishing gloriously eight wars, all righteously undertaken, and all honourably terminated; namely, 1st, The civil war with Ish-bosheth: 2d, The war against the Jebusites: 3d, Against the Philistines and their allies: 4th, Against the Philistines alone: 5th, Against the Moabites: 6th, Against Hadadezer: 7th, Against the Idumeans: 8th, Against the Ammonites and Syrians. We shall soon see this last entirely completed, by the conquest of the kingdom of the Ammonites, abandoned by their allies. What glory for the monarch of Israel, had not the splendour of this illustrious epocha been obscured by a complication of crimes, of which one could never have even suspected him! See Delaney.
