'Tops' in the Bible

The lords of Shechem rebelled against him by putting people on the tops of the mountains to ambush and rob everyone who passed by them on the road. So this was reported to Abimelech.

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 are seeing the shadow of the mountains as if they were men.”
