1 Kings 20:29

And they pitched one over against the other seven days
Very probably the Israelites pitched upon an hill, and the Syrians waited till they changed their position, not caring to fall upon them, though so very supernumerary to them, for the reason before given:

and so it was, that in the seventh day the battle was joined;
or they that made war drew nigh, as the Targum, and both sides engaged in battle:

and the children of Israel slew of the Syrians 100,000 footmen in one
day;
which was a prodigious slaughter to be made by so small an army; the hand of the Lord was visible in it.
