Judges 9:33-35

33Then in the morning, as soon as the sun is up, rise early and rush upon the city. And when he and the people who are with him come out against you, you may do to them as your hand finds to do."

34So Abimelech and all the men who were with him rose up by night and set an ambush against Shechem in four companies.

35And Gaal the son of Ebed went out and stood in the entrance of the gate of the city, and Abimelech and the people who were with him rose from the ambush.
