Window
properly only an opening in a house for the admission of light and air, covered with lattice-work, which might be opened or closed (2 Kings 1:2; Acts 20:9). The spies in Jericho and Paul at Damascus were let down from the windows of houses abutting on the town wall (Josh. 2:15; 2 Cor. 11:33). The clouds are metaphorically called the "windows of heaven" (Gen. 7:11; Mal. 3:10). The word thus rendered in Isa. 54:12 ought rather to be rendered "battlements" (LXX., "bulwarks;" R.V., "pinnacles"), or as Gesenius renders it, "notched battlements, i.e., suns or rays of the sun"= having a radiated appearance like the sun.
