Judges 9:32

29 If only I had authority over this people! I would put Abimelech out of the way, and I would say to Abimelech, Make your army strong, and come out.

30 Now Zebul, the ruler of the town, hearing what Gaal, the son of Ebed, had said, was moved to wrath.

31 And he sent to Abimelech at Arumah, saying, See, Gaal, the son of Ebed, and his brothers have come to Shechem, and they are working up the town against you.

32 So now, get up by night, you and your people, and keep watch in the field secretly;

33 And in the morning, when the sun is up, get up early and make a rush on the town; and when he and his people come out against you, do to them whatever you have a chance to do.

34 So Abimelech and the people with him got up by night, in four bands, to make a surprise attack on Shechem.

35 And Gaal, the son of Ebed, went out, and took his place at the doorway into the town; then Abimelech and his people got up from the place where they had been waiting.
