Judges 9:34-36

Abimelech and his troops, four companies of them, went up that night and waited in ambush approaching Shechem. Gaal son of Ebed had gotten up and was standing in the city gate. Abimelech and his troops left their cover. When Gaal saw them he said to Zebul, “Look at that, people coming down from the tops of the mountains!” Zebul said, “That’s nothing but mountain shadows; they just look like men.” Gaal kept chattering away.
