During the thirty-sixth year of Asa's reign, King Baasha of Israel invaded Judah and interdicted Ramah by building fortifications around it so no one could enter or leave to join King Asa of Judah.

and after several years went down to visit Ahab in Samaria. Ahab slaughtered many sheep and cattle to honor Jehoshaphat and those who came with him. He persuaded him to join in an attack against Ramoth Gilead.

King Ahab of Israel asked King Jehoshaphat of Judah, "Will you join me in attacking Ramoth-gilead?"

"I'm with you," Jehoshaphat replied. "and my army is with you. We'll join you in the battle." But then Jehoshaphat asked the king of Israel, "Please ask for a message from the LORD, first."

And after this did Jehoshaphat king of Judah join himself with Ahaziah king of Israel, who did very wickedly:

And he will join himself with him to make ships to go to Tarshish: and they will make the ships in Ezion-Geber.
