When the king of Ai saw the Israelites, he hurried out early in the morning with the men of the city to engage them in battle at an appointed place overlooking the Arabah. But he did not know that an ambush had been set up against him behind the city.
KJV
And it came to pass, when the king of Ai saw [it], that they hasted and rose up early, and the men of the city went out against Israel to battle, he and all his people, at a time appointed, before the plain; but he wist not that [there were] liers in ambush against him behind the city.
