1 Chronicles 19:7

⁵  Then there went certain, and told David how the men were served. And he sent to meet them: for the men were greatly ashamed. And the king said, Tarry at Jericho until your beards be grown, and then return.

⁶  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 Syriamaachah, and out of Zobah.

⁷  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.

⁸  And when David heard of it, he sent Joab, and all the host of the mighty men.

⁹  And the children of Ammon came out, and put the battle in array before the gate of the city: and the kings that were come were by themselves in the field.
