Judges 9:33-35

33And it shall be, that in the morning, as soon as the sun is up, thou shalt rise early, and set upon the city: and, behold, when he and the people that is with him come out against thee, then mayest thou do to them as thou shalt find occasion.1

34And Abimelech rose up, and all the people that were with him, by night, and they laid wait against Shechem in four companies. 35And Gaal the son of Ebed went out, and stood in the entering of the gate of the city: and Abimelech rose up, and the people that were with him, from lying in wait.
