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.

Commentary on 2 Samuel 10:1-5
(Read 2 Samuel 10:1-5)
Nahash had been an enemy to Israel, yet had showed kindness to David. David therefore resolves gratefully to return it. If a Pharisee gives alms in pride, though God will not reward it, yet he that receives the alms ought to return thanks for it. Those who bear ill-will to their neighbours, are resolved not to believe that their neighbours bear any good-will to them. There is nothing so well meant, but it may be ill interpreted, and is wont to be so, by men who love nobody but themselves. The best men must not think it strange if they are thus misrepresented. Charity thinketh no evil. According to the usages of those days and countries, Hanun treated David's ambassadors in the most contemptuous manner. David showed much concern for his servants. Let us learn not to lay unjust reproaches to heart; they will wear off, and turn only to the shame of those who utter or do them; while the reputation wrongfully hurt in a little time grows again, as these beards did. God will bring forth thy righteousness as the light, therefore wait patiently for him, Psalm 37:6,7.
