1 Kings 20:23-30 New King James Version (NKJV)
The Syrians Again Defeated
23 Then the servants of the king of Syria said to him, “Their gods are gods of the hills. Therefore they were stronger than we; but if we fight against them in the plain, surely we will be stronger than they. 24 So do this thing: Dismiss the kings, each from his position, and put captains in their [a]places; 25 and you shall muster an army like the army [b]that you have lost, horse for horse and chariot for chariot. Then we will fight against them in the plain; surely we will be stronger than they.”
And he listened to their voice and did so.
26 So it was, in the spring of the year, that Ben-Hadad mustered the Syrians and went up to Aphek to fight against Israel. 27 And the children of Israel were mustered and given provisions, and they went against them. Now the children of Israel encamped before them like two little flocks of goats, while the Syrians filled the countryside.
28 Then a man of God came and spoke to the king of Israel, and said, “Thus says the Lord: ‘Because the Syrians have said, “The Lord is God of the hills, but He is not God of the valleys,” therefore I will deliver all this great multitude into your hand, and you shall know that I am the Lord.’ ” 29 And they encamped opposite each other for seven days. So it was that on the seventh day the battle was joined; and the children of Israel killed one hundred thousand foot soldiers of the Syrians in one day. 30 But the rest fled to Aphek, into the city; then a wall fell on twenty-seven thousand of the men who were left.
And Ben-Hadad fled and went into the city, into an inner chamber.
1 Kings 20:23-30 New International Version (NIV)
23 Meanwhile, the officials of the king of Aram advised him, “Their gods are gods of the hills. That is why they were too strong for us. But if we fight them on the plains, surely we will be stronger than they. 24 Do this: Remove all the kings from their commands and replace them with other officers. 25 You must also raise an army like the one you lost—horse for horse and chariot for chariot—so we can fight Israel on the plains. Then surely we will be stronger than they.” He agreed with them and acted accordingly.
26 The next spring Ben-Hadad mustered the Arameans and went up to Aphek to fight against Israel. 27 When the Israelites were also mustered and given provisions, they marched out to meet them. The Israelites camped opposite them like two small flocks of goats, while the Arameans covered the countryside.
28 The man of God came up and told the king of Israel, “This is what the Lord says: ‘Because the Arameans think the Lord is a god of the hills and not a god of the valleys, I will deliver this vast army into your hands, and you will know that I am the Lord.’”
29 For seven days they camped opposite each other, and on the seventh day the battle was joined. The Israelites inflicted a hundred thousand casualties on the Aramean foot soldiers in one day. 30 The rest of them escaped to the city of Aphek, where the wall collapsed on twenty-seven thousand of them. And Ben-Hadad fled to the city and hid in an inner room.
