Genesis 1:7-9

1:7 And God made the firmament, and divided the waters which [were] under the firmament from the waters which [were] above the firmament: and it was so. 1:8 And God called the firmament Heaven. And the evening and the morning were the second day. 1:9 And God said, Let the waters under the heaven be gathered together unto one place, and let the dry [land] appear: and it was so.
