But Jehoshaphat said, “Is there not yet a prophet of the Lord here that we may inquire of him?”

But Jehoshaphat said, “Is there not a prophet of the Lord here, that we may inquire of the Lord by him?” And one of the king of Israel’s servants answered and said, “Elisha the son of Shaphat is here, who used to pour water on the hands of Elijah.”

But Jehoshaphat said, “Is there not yet a prophet of the Lord here that we may inquire of him?”

But a prophet of the Lord was there, whose name was Oded; and he went out to meet the army which came to Samaria and said to them, “Behold, because the Lord, the God of your fathers, was angry with Judah, He has delivered them into your hand, and you have slain them in a rage which has even reached heaven.
