2 Chronicles 18:4-6

New International Version

⁴ But Jehoshaphat also said to the king of Israel, “First seek the counsel of the Lord.”

⁵ So the king of Israel brought together the prophets—four hundred men—and asked them, “Shall we go to war against Ramoth Gilead, or shall I not?”

“Go,” they answered, “for God will give it into the king’s hand.”

⁶ But Jehoshaphat asked, “Is there no longer a prophet of the Lord here whom we can inquire of?”
