Does the rainbow appear in the New Testament?
Yes — twice in Revelation. Rev 4:3 describes a rainbow (G2463 iris) encircling the throne; Rev 10:1 crowns the mighty angel with one. Both trace to a chain: Gen 9:13 (H7198 qeshet + H6051 anan) → Ezk 1:28 (same Hebrew pair, unique to these two OT pericopes) → LXX toxon bridge → John's iris. The Noahic war-bow retired into the cloud reappears encircling the throne of the Lamb.
The short answer is yes — and the canonical chain that gets it there is precise enough to verify step by step.
The two NT appearances
Revelation 4:3 describes the throne:
καὶ ἶρις κυκλόθεν τοῦ θρόνου ὅμοιος ὁράσει σμαραγδίνῳ
"And a rainbow (iris) around the throne, like an emerald in appearance." — Rev 4:3
Revelation 10:1 describes the mighty angel descending:
περιβεβλημένον νεφέλην καὶ ἡ ἶρις ἐπὶ τῆς κεφαλῆς αὐτοῦ
"Clothed with a cloud, and the rainbow on his head." — Rev 10:1
The Greek noun is G2463 iris — the standard Greek word for the meteorological rainbow. John deploys it twice in the throne-vision chapters, and both times the rainbow appears in close association with the cloud (nephelē).
The OT chain that gets here
The connection does not appear by accident. Genesis 9:13 established a unique pairing: H7198 qeshet (the bow — warrior's bow in 72 of 76 OT uses) + H6051 anan (cloud). That specific two-noun combination appears in exactly two locations in the entire OT. The first is Genesis 9:13-16 — the Noahic covenant sign. The second is Ezekiel 1:28:
כְּמַרְאֵ֣ה הַקֶּ֡שֶׁת אֲשֶׁר֩ יִהְיֶ֨ה בֶעָנָ֜ן
"Like the appearance of the qeshet that is in the cloud." — Ezk 1:28
Ezekiel is describing what surrounds the divine throne-chariot (merkavah) — the rainbow-bow encircling the kabod of YHWH. He is not reaching for a stock weather image. He is citing Gen 9:13 by its exact two-noun pairing. The qeshet + anan construction is unique to these two pericopes. When Ezekiel uses it, he means for the reader to hear Noah.
The LXX bridge
The Greek translators rendered H7198 qeshet as G5115 toxon — the standard Greek war-bow/hunter-bow noun — in BOTH the Genesis rainbow verses and the warrior-bow verses. They used the same noun for both senses, following the Hebrew. LXX Gen 9:13 has toxon; LXX Ezk 1:28 has toxon.
When John writes Revelation, he shifts to G2463 iris — the meteorological rainbow word in common Greek. That is the standard NT pattern: the source passage (Gen 9) is unmistakable; the surface term shifts in the translation idiom. The vocabulary chain runs:
Gen 9:13 (qeshet + anan) → Ezk 1:28 (qeshet + anan) → LXX toxon (both verses) → Rev 4:3 / 10:1 (iris kyklothen tou thronou / iris epi tēs kephalēs)
What it means that the bow encircles the throne
In Genesis 9, God retired the weapon — et qashti natatti be-anan, "my qeshet I have given in the cloud." The bow that had drawn on the world in the Flood was hung up as the sign of the oath not to destroy again. The image is a victor laying down his weapons.
In Revelation 4, the retired weapon encircles the throne. The bow that was a weapon becomes the surrounding glory. The Noahic covenant's sign — the visible retirement of divine judgment — frames the throne of the Lamb. The qeshet moved from the post-Flood cloud to the eternal throne-room; the trajectory runs from Ararat to the new creation.
A detail from Revelation 10
Rev 10:1's angel descends clothed with a cloud (peribeblēmenon nephelēn) and crowned with the rainbow (iris). The cloud-and-rainbow pairing is deliberate Noahic allusion — both nouns from the Gen 9 formula (qeshet + anan) appear together in John's angel-description as they appear together in Gen 9:14: ve-nir'atah ha-qeshet be-anan ("and the qeshet shall be seen in the cloud"). The angel clothed in cloud, crowned in rainbow, is dressed in the covenant vocabulary.
The full study develops the qeshet semantic field and Ezekiel's throne-vision in Rainbow and Curse.
Did God curse Africans? What does the Bible actually say?
No. Gen 9:25 curses Canaan, not Ham, and not Ham's African descendants. MT, SP, and LXX — three independent witnesses — all read arur Kena'an. The 17th-19th century "curse of Ham" defense of African slavery has zero textual support. The text does not name Ham, does not identify Ham with Africa, does not mention skin color, and does not extend the curse beyond Canaan's Levantine descendants.
Is the rainbow really a weapon?
In Hebrew, yes — H7198 qeshet is the standard noun for a warrior's or hunter's bow in 72 of its 76 OT occurrences (94.7%). The LXX renders it G5115 toxon, the Greek war-bow word. When God says "my qeshet I have given in the cloud" at Gen 9:13, the Hebrew imagination reads a weapon retired — not a meteorological badge.
What did Ham actually do to Noah?
He saw his father's nakedness and told his brothers (Gen 9:22). The Hebrew uses H7200 ra'ah (see) + H5046 nagad (tell). The Mosaic incest formula always uses H1540 galah (uncover) + H6172 ervah — 33 OT co-occurrences. Gen 9:22 stops short of the galah-verb. The sexual-violation reading is inference from inter-textual harmonization, not what the Hebrew text of Gen 9:22 says.
What does "eternal covenant" mean — and where else does it appear?
H5769 berit olam ("eternal covenant") appears first at Gen 9:16 for the rainbow covenant. The LXX renders it diatheke aionios — and that Greek phrase travels through Sir 44:18, Bar 2:35, and lands at Heb 13:20, where the writer applies it to Christ's resurrection as the blood of "the eternal covenant." The phrase carries its Noahic provenance across 2,000 years of canonical and deuterocanonical tradition.
