Judges 9:33-35

33So it will be in the morning, as soon as the sun is up, you will rise early and advance on the city; and behold, when he and the people who are with him come out against you, then you should do to them whatever your hand finds.”

34So Abimelech and all the people who were with him rose up by night and lay in wait against Shechem in four columns.

35Now Gaal son of Ebed went out and stood at the entrance of the city gate. Then Abimelech and the people who were with him emerged from the ambush.
