For three years there was no war between Aram and Israel.
In the third year King Jehoshaphat of Judah went to visit the king of Israel.
The king of Israel asked his staff, "Do you know that Ramoth in Gilead belongs to us, and we are doing nothing to take it back from the king of Aram?"
Then he asked Jehoshaphat, "Will you go with me to fight at Ramoth in Gilead?" Jehoshaphat told the king of Israel, "I will do what you do. My troops will do what your troops do. My horses will do what your horses do."
Then Jehoshaphat said to the king of Israel, "But first, find out what the word of the LORD is [in this matter]."
So the king of Israel called 400 prophets together. He asked them, "Should I go to war against Ramoth in Gilead or not?" "Go," they said. "The Lord will hand over Ramoth to you."
But Jehoshaphat asked, "Isn't there a prophet of the LORD whom we could ask?"
