2 Kings 3:7

Joram sent messengers to Jehoshaphat, the king of Judah. Joram said, “The king of Moab has broken away from my rule. Will you go with me to fight against Moab?” Jehoshaphat said, “Yes, I will go with you. We will join together as one army. My people will be like your people, and my horses will be like your horses.”
