Yahweh brought him outside, and said, “Look now toward the sky, and count the stars, if you are able to count them.” He said to Abram, “So will your seed be.”

Quotation1
A formal citation — high verbal volume, often introduced by a saying-formula.
Quoted verbatim in 4:18: 'So will your seed be' (Genesis 15:5 LXX, 'houtos estai to sperma sou'), the star-promise spoken immediately before Genesis 15:6. Paul binds the two halves of Genesis 15 together: the promise (v.5) and Abraham's believing response reckoned as righteousness (v.6).
High confidenceAllusion2
A deliberate verbal borrowing without a citation formula.
‘As many as the stars of the sky’ (v. 12) lifts the star-promise of Gen 15:5. Recurrence is decisive: the paired ‘stars… and sand’ formula returns from Gen 22:17, and the same image already anchored 6:13–14 — the most-repeated promise to Abraham.
High confidenceThe Abrahamic promise: "count the stars, if you are able to count them... so shall your offspring be" — the uncountable, innumerable seed. John's "a great multitude, which no man could count" (hon arithmesai auton oudeis edynato) directly fulfills the count-if-you-can promise, now extended beyond Israel to every nation. Strong on volume and on John's larger Abrahamic-fulfillment logic (the multitude completes what the sealed 144,000 represent).
High confidenceEcho2
A fainter, low-volume reuse, carried by recurrence or thematic coherence.
The promise that Abraham's offspring would be innumerable underwrites the privileged status Paul invokes by naming himself 'seed of Abraham.' The verse is the classic charter of the lineage to which the opponents and Paul both lay claim. Coherence is high; verbal volume modest.
Medium confidenceAbraham's innumerable offspring like the stars faintly grounds the 'many will come... with Abraham' multitude; thematic, contested.
