Judges 9:35-36

35Now Gaal the son of Ebed came out and stood in the entrance of the city gate; then Abimelech and the people who were with him got up from the ambush.

36When Gaal saw the people, he said to Zebul, “Look, people are coming down from the mountaintops.” But Zebul said to him, “You are only seeing the shadow of the mountains as if they were men.”
