'Windows' in the Bible

Then it will be that he who flees at the sound of terror will fall into the pit,And he who comes up out of the pit will be caught in the snare;For the windows of heaven are opened, and the foundations of the earth tremble.

“And I will make your battlements of rubies,And your gates of [shining] beryl stones,And all your [barrier] walls of precious stones.

“Who are these who fly like a cloudAnd like doves to their windows?
