2 Samuel 10:4

1 Now after this, death came to the king of the children of Ammon, and Hanun, his son, became king in his place.

2 And David said, I will be a friend to Hanun, the son of Nahash, as his father was a friend to me. So David sent his servants, to give him words of comfort on account of his father. And David's servants came into the land of the children of Ammon.

3 But the chiefs of the children of Ammon said to Hanun their lord, Does it seem to you that David is honouring your father by sending comforters to you? has he not sent his servants to go through the town and make secret observation of it, and overcome it?

4 So Hanun took David's servants, and after cutting off half the hair on their chins, and cutting off the skirts of their robes up to the middle, he sent them away.

5 When David had news of it, he sent men out with the purpose of meeting them on their way, for the men were greatly shamed: and the king said, Go to Jericho till your hair is long again, and then come back.

6 And when the children of Ammon saw that they had made themselves hated by David, they sent to the Aramaeans of Beth-rehob and Zobah, and got for payment twenty thousand footmen, and they got from the king of Maacah a thousand men, and from Tob twelve thousand.

7 And hearing of this, David sent Joab and all the army and the best fighting-men.
