David said, I will show kindness to Hanun the son of Nahash, because his father shown kindness to me. So David sent messengers to comfort him concerning his father. David's servants came into the land of the children of Ammon to Hanun, to comfort him.
There is, however, one sin of David’s that the Chronicler does record, and that is his numbering of the people. Yet even this story is recorded not to point out a personal weakness, but to show how David bought the piece of ground on which the temple was to be built (21:1-22:1; see notes on 2 Samuel 24:1-25). The writer now moves on to show how David, having bought the site, began preparations for the temple’s construction.
