So Solomon observed the Festival of Tents at that time, as did all of Israel with him. A large assembly came up from as far away as Lebo-hamath and the Wadi of Egypt to appear in the presence of the LORD our God, not just for seven days, but for seven days after that, a total of fourteen days.

So they remained in opposing camps for seven days. Then on the seventh day the battle commenced, and the Israelis killed 100,000 Aramean infantry troops in a single day.
