David said, "I will deal loyally with Hanun son of Nahash, for his father dealt loyally with me." So David sent messengers to console him concerning his father. When David's servants came to Hanun in the land of the Ammonites, to console him,
the officials of the Ammonites said to Hanun, "Do you think, because David has sent consolers to you, that he is honoring your father? Have not his servants come to you to search and to overthrow and to spy out the land?"
and they departed. When David was told about the men, he sent messengers to them, for they felt greatly humiliated. The king said, "Remain at Jericho until your beards have grown, and then return."
When the Ammonites saw that they had made themselves odious to David, Hanun and the Ammonites sent a thousand talents of silver to hire chariots and cavalry from Mesopotamia, from Aram-maacah and from Zobah.
They hired thirty-two thousand chariots and the king of Maacah with his army, who came and camped before Medeba. And the Ammonites were mustered from their cities and came to battle.
When Joab saw that the line of battle was set against him both in front and in the rear, he chose some of the picked men of Israel and arrayed them against the Arameans;
But when the Arameans saw that they had been defeated by Israel, they sent messengers and brought out the Arameans who were beyond the Euphrates, with Shophach the commander of the army of Hadadezer at their head.
When David was informed, he gathered all Israel together, crossed the Jordan, came to them, and drew up his forces against them. When David set the battle in array against the Arameans, they fought with him.
The Arameans fled before Israel; and David killed seven thousand Aramean charioteers and forty thousand foot soldiers, and also killed Shophach the commander of their army.
When the servants of Hadadezer saw that they had been defeated by Israel, they made peace with David, and became subject to him. So the Arameans were not willing to help the Ammonites any more.
