1 Kings 20:11 In-Context

9 So Ahab replied to Benhadad's messengers, "Tell my lord the king that I agreed to his first demand, but I cannot agree to the second." The messengers left and then returned with another message
10 from Benhadad: "I will bring enough men to destroy this city of yours and carry off the rubble in their hands. May the gods strike me dead if I don't!"
11 King Ahab answered, "Tell King Benhadad that a real soldier does his bragging [after] a battle, not before it."
12 Benhadad received Ahab's answer as he and his allies, the other rulers, were drinking in their tents. He ordered his men to get ready to attack the city, and so they moved into position.
13 Meanwhile, a prophet went to King Ahab and said, "The Lord says, "Don't be afraid of that huge army! I will give you victory over it today, and you will know that I am the Lord.' "
