Exodus Exodus 11:1-10
The whole chapter narrows to a single silence: on the night Egypt will scream, not a dog will so much as growl at Israel — the audible proof that YHWH distinguishes between the two peoples, the distinction climaxing at last on the firstborn.
Exodus Exodus 10:1-29
At the ninth plague the God who said 'let there be light' says 'let there be darkness' — the same jussive, the opposite noun — and Egypt reverts to the uncreated dark while Israel keeps the only light in all of Exodus.
Genesis · Numbers · Job · Psalms · Isaiah · Daniel · Matthew · Revelation Genesis 1:16; 15:5; Numbers 24:17; Job 38:7; Isaiah 14:12; Daniel 12:3; Matthew 2:1-2; Revelation 22:16
God made the stars in a single clause of Genesis 1, and from that fact the whole canon builds: stars as covenant seed, as rulers, as the angelic host, as judgment, as forbidden worship. The fallen king of Babylon claimed the title and fell. Christ closes the arc: I am the bright morning star.
Genesis 19:1-29
Two angels arrive at Sodom's gate at evening; Lot welcomes them with the same hospitality verbs Abraham used at Mamre — prostration, foot-washing, unleavened bread — and the city replies with a sentence Judges 19 will quote back word-for-word. Fire and brimstone fall from Yahweh from Yahweh out of the heavens, coining the canonical vocabulary the Psalter abstracts, Ezekiel projects, Jesus quotes, and Revelation deploys six times for the lake of fire. The chapter closes with the formula that closed the Flood: God remembered Abraham, and Lot was sent out from the midst of the Overthrow.
Revelation 17:1-18:24
Revelation 21:23
The Lamb is not called 'light' in Revelation 21:23. He is called 'lamp' — a device that holds and transmits light from another source. John's vocabulary for light, luminaries, and radiance is remarkably varied, and the distinctions are not decorative. They are the theology.
