1 Chronicles 19:6–7

When the Ammonites saw that they had become a stench to David, Hanun and the Ammonites sent 1,000 talents of silver to hire chariots and horsemen from Mesopotamia, from Aram-maacah, and from Zobah. They hired 32,000 chariots and the king of Maacah with his army, who came and encamped before Medeba. And the Ammonites were mustered from their cities and came to battle.

When the Ammonites realized that they had become obnoxious to David, Hanun and the Ammonites sent a thousand talents of silver to hire chariots and charioteers from Aram Naharaim, Aram Maakah and Zobah. They hired thirty-two thousand chariots and charioteers, as well as the king of Maakah with his troops, who came and camped near Medeba, while the Ammonites were mustered from their towns and moved out for battle.

When the Ammonites realized they had made themselves repulsive to David, Hanun and the Ammonites sent thirty-eight tons of silver to hire chariots and horsemen from Aram-naharaim, Aram-maacah, and Zobah. They hired thirty-two thousand chariots and the king of Maacah with his army, who came and camped near Medeba. The Ammonites also came together from their cities for the battle.

When the people of Ammon realized how seriously they had angered David, Hanun and the Ammonites sent 75,000 pounds of silver to hire chariots and charioteers from Aram-naharaim, Aram-maacah, and Zobah. They also hired 32,000 chariots and secured the support of the king of Maacah and his army. These forces camped at Medeba, where they were joined by the Ammonite troops that Hanun had recruited from his own towns.

And when the Ammonites saw that they made themselves odious to David, Hanun and the Ammonites sent one thousand talents of silver to hire for themselves horses and chariots from Aram-Naharaim, Aram-Maacah, and Zobah. And they hired for themselves thirty-two thousand chariots and the king of Maacah and his people, and they came and encamped before Medeba. And the Ammonites were gathered from their cities and came to the battle.

And when the children of Ammon saw that they had made themselves odious to David, Hanun and the children of Ammon sent a thousand talents of silver to hire them chariots and horsemen out of Mesopotamia, and out of Syria-maachah, and out of Zobah. So they hired thirty and two thousand chariots, and the king of Maachah and his people; who came and pitched before Medeba. And the children of Ammon gathered themselves together from their cities, and came to battle.
