'Firmament of the Heavens' in the Bible

And God will say there shall be lights in the firmament of the heavens to separate between the day and between the night: and they shall be for signs and for set times, and for days and for years.

And they shall be for lights in the firmament of the heavens to give light upon the earth: and it shall be so.

And God will give them in the firmament of the heavens to give light upon the earth.

And God will say the waters shall breed abundantly creeping things, the living soul, and birds shall fly over the earth, over the face of the firmament of the heavens.
