2 Samuel 10:2-7

10:2 David said, “I will express my loyalty to Hanun son of Nahash just as his father was loyal to me.” So David sent his servants with a message expressing sympathy over his father’s death. When David’s servants entered the land of the Ammonites, 10:3 the Ammonite officials said to their lord Hanun, “Do you really think David is trying to honor your father by sending these messengers to express his sympathy? No, David has sent his servants to you to get information about the city and spy on it so they can overthrow it!”

10:4 So Hanun seized David’s servants and shaved off half of each one’s beard. He cut the lower part of their robes off so that their buttocks were exposed, and then sent them away. 10:5 Messengers told David what had happened, so he summoned them, for the men were thoroughly humiliated. The king said, “Stay in Jericho until your beards have grown again; then you may come back.”

10:6 When the Ammonites realized that David was disgusted with them, they sent and hired 20,000 foot soldiers from Aram Beth Rehob and Aram Zobah, in addition to 1,000 men from the king of Maacah and 12,000 men from Ish-tob.

10:7 When David heard the news, he sent Joab and the entire army to meet them.
