he fled before
1 Kings 20:18-21
18
And he saith, 'If for peace they have come out -- catch them alive; and if for battle they have come out -- alive catch them.'
19
And these have gone out of the city -- the young men of the heads of the provinces -- and the force that [is] after them,
20
and smite each his man, and Aram fleeth, and Israel pursueth them, and Ben-Hadad king of Aram escapeth on a horse, and the horsemen;
21
and the king of Israel goeth out, and smiteth the horses, and the charioteers, and hath smitten among the Aramaeans a great smiting.
1 Kings 20:30-21
