Moses
Genesis 1:8BSB·traditional attribution

God called the expanse “sky.” And there was evening, and there was morning—the second day.

Matthew Henry Presbyterian

The firmament is not a wall that shuts heaven off from earth but a way of intercourse between them. God appointed the air to be the vehicle of light's beams and the medium by which the invisible world communicates with the visible, spanning that vast distance yet leaving passage open.

Keil & Delitzsch Lutheran

The firmament stretches out as a wall of separation through the chaotic waters, dividing upper from lower. Those above are not ethereal waters beyond the atmosphere but the waters that gather in clouds and pour down as rain when the windows of heaven open.

John Gill Reformed Baptist

God called the expanse heaven, which reaches to the third heaven itself and includes the starry and airy regions. Evening and morning made the second day, a full twenty-four hours, yet notice the sacred formula 'and God saw that it was good' does not close this day's work as it does the others, because the waters were not perfected until the third day.
