In Genesis 1:9, God gathers the waters below the sky into one place to reveal dry land — the next step after the waters were separated by the vault here.

In Genesis 1:20, birds are created to fly across this firmament.

In Genesis 1:15, the firmament created here is where lights are placed for the earth.

Genesis 7:11 reverses this separation, unleashing waters in judgment.

In Job 26:8, God 'binds up the waters in his thick clouds' so they don't burst open — a poetic parallel to the firmament holding back the waters above here.

In Psalm 148:4, the psalmist calls 'waters above the heavens' to praise God — directly invoking the waters placed above the vault in this act of creation.

In Proverbs 8:28, Wisdom recalls this same act — God 'made firm the skies above' — as part of her testimony to being present when God established the heavens.

In Proverbs 8:29, Wisdom describes God assigning the sea its limit so waters 'not transgress his command' — echoing the boundary-setting of this water separation.

Job 9:8 references God spreading the heavens, echoing this act.
