Judges 9:35-36

35When Gaal the son of Ebed went out and stood in the entrance to the city gate, Abimelech and the people who were with him rose from lying in wait.

36And when Gaal saw the people, he said to Zebul, “Look, people are coming down from the tops of the mountains!” But Zebul said to him, “You see the shadows of the mountains as if they were men.”
