Israel and Syria fought one another in battle, but before the battle took place, the writer of First Kings wrote:

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. 

– 1 Kings 20.29

Is there any significance to seven days here? I don’t think so. If so, what is the connection. What would seven or perfection represent in this case?
