'Arch' in the Bible

And God said, Let there be a solid arch stretching over the waters, parting the waters from the waters.

And God made the arch for a division between the waters which were under the arch and those which were over it: and it was so.

And God gave the arch the name of Heaven. And there was evening and there was morning, the second day.

And God said, Let there be lights in the arch of heaven, for a division between the day and the night, and let them be for signs, and for marking the changes of the year, and for days and for years:

And let them be for lights in the arch of heaven to give light on the earth: and it was so.

And God put them in the arch of heaven, to give light on the earth;

And God said, Let the waters be full of living things, and let birds be in flight over the earth under the arch of heaven.
