So Yehoshua arose, and all the people of war, to go up to `Ai: and Yehoshua chose out thirty thousand men, the mighty men of valor, and sent them forth by night.
He sent messengers to Avimelekh craftily, saying, Behold, Ga`al the son of `Eved and his brothers are come to Shekhem; and behold, they constrain the city [to take part] against you.
and it shall be, that in the morning, as soon as the sun is up, you shall rise early, and rush on the city; and behold, when he and the people who are with him come out against you, then may you do to them as you shall find occasion.
