2 Samuel 10:5-7

Amplified Bible

⁵ When David was informed, he sent [messengers] to meet them [before they reached Jerusalem], for the men were greatly ashamed and humiliated. And the king said, “Stay at Jericho until your beards grow, and then return.”

⁶ When the Ammonites saw that they had become an object of hatred to David, they sent word and hired the Arameans (Syrians) of Beth-rehob and the Arameans of Zobah, 20,000 foot soldiers, and the king of Maacah with 1,000 men, and the men of Tob with 12,000 men [to fight for them]. ⁷ When David heard about it, he sent Joab and the entire army, the strong and brave men.
