2 Chronicles 18:2-3

2A few years later he went to visit Ahab in Samaria. Ahab slaughtered many sheep and cattle for a banquet in honor of Jehoshaphat and the people who were with him. And Ahab persuaded Jehoshaphat to attack Ramoth in Gilead with him.

3King Ahab of Israel asked King Jehoshaphat of Judah, “Will you go with me to Ramoth in Gilead?” Jehoshaphat told the king of Israel, “I will do what you do. My troops will do what your troops do. ⌞We will join⌟ your troops in battle.”
