2 Samuel 10:2

Then said David, I will shew kindness unto Hanun the son of Nahash, as his father shewed kindness unto me. And David sent to comfort him by the hand of his servants for his father. And David's servants came into the land of the children of Ammon.

I will show kindness unto Hanun, the son of Nahash, as his father showed kindness unto me. It is probable that this was the Nahash against whom Saul waged war at Jabesh-gilead (1 Samuel 11:11). David, on leaving Gath, where his life was exposed to danger, found an asylum with the king of Moab; and as Nahash, king of the Ammonites, was his nearest neighbour, it may be that, during the feud between Saul and David, he, through enmity to the former, was kind and hospitable to David.
