'Hired' in the Bible

When the Ammonites realized they had become repulsive to David, they hired 20,000 foot soldiers from the Arameans of Beth-rehob and Zobah, 1,000 men from the king of Maacah, and 12,000 men from Tob.

Then he went to the king and said, “Your servant has just hired sheepshearers. Will the king and his servants please come with your servant?”
