Judges 9:35

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.

36 And when Gaal saw the people, he said to Zebul, See! people are coming down from the tops of the mountains. And Zebul said to him, You see the shade of the mountains like men.

37 And Gaal said again, See! people are coming down from the middle of the land, and one band is coming by way of the oak-tree of the Seers.

38 Then Zebul said to him, Now where is your loud talk when you said, Who is Abimelech that we are to be his servants? Is this not the people whom you were rating so low? Go out now, and make war on them.
