2 Samuel 10:1-6

1 David Defeats the Ammonites
In the course of time, the king of the Ammonites died, and his son Hanun succeeded him as king.

2 David thought, “I will show kindness to Hanun son of Nahash, just as his father showed kindness to me.” So David sent a delegation to express his sympathy to Hanun concerning his father.
When David’s men came to the land of the Ammonites,

3 the Ammonite nobles said to Hanun their lord, “Do you think David is honoring your father by sending men to you to express sympathy? Hasn’t David sent them to you to explore the city and spy it out and overthrow it?”

4 So Hanun seized David’s men, shaved off half of each man’s beard, cut off their garments in the middle at the buttocks, and sent them away.

5 When David was told about this, he sent messengers to meet the men, for they were greatly humiliated. The king said, “Stay at Jericho till your beards have grown, and then come back.”

6 When the Ammonites realized that they had become a stench in David’s nostrils, they hired twenty thousand Aramean foot soldiers from Beth Rehob and Zobah, as well as the king of Maacah with a thousand men, and also twelve thousand men from Tob.
