2 Chronicles 18:2-4

New Revised Standard Version, Anglicised Catholic Edition

² After some years he went down to Ahab in Samaria. Ahab slaughtered an abundance of sheep and oxen for him and for the people who were with him, and induced him to go up against Ramoth-gilead. ³ King Ahab of Israel said to King Jehoshaphat of Judah, ‘Will you go with me to Ramoth-gilead?’ He answered him, ‘I am with you, my people are your people. We will be with you in the war.’

⁴ But Jehoshaphat also said to the king of Israel, ‘Inquire first for the word of the Lord.’
