1 Chronicles 19:2-5

2And David said, I will shew kindness to Hanun the son of Nahash, because his father shewed kindness to me. And David sent messengers to comfort him concerning his father. And David's servants came into the land of the children of Ammon to Hanun, to comfort him.

3And the princes of the children of Ammon said to Hanun, Is it, in thine eyes, to honour thy father that David has sent comforters to thee? Is it not to search and overthrow, and to spy out the land that his servants are come to thee?

4And Hanun took David's servants, and had them shaved, and their raiment cut off in the midst, as far as the hip, and sent them away.

5And [certain] went and told David concerning the men; and he sent to meet them, for the men were greatly ashamed. And the king said, Abide at Jericho until your beards be grown, and then return.
