15Yahweh’s angel called to Abraham a second time out of the sky,16and said, “ ‘I have sworn by myself,’ says Yahweh, ‘because you have done this thing, and have not withheld your son, your only son,17that I will bless you greatly, and I will multiply your offspring greatly like the stars of the heavens, and like the sand which is on the seashore. Your offspring will possess the gate of his enemies.18All the nations of the earth will be blessed by your offspring, because you have obeyed my voice.’ ”
The counter-reading
How this passage is read within its own context.
On the critical reading, Genesis 22:18 restates the standard Abrahamic blessing formula, here grounded explicitly in Abraham's obedience during the Aqedah, and the Hebrew 'zera' (offspring/seed) is a collective noun referring to Abraham's descendants as a people. In this view Paul's insistence at Galatians 3:16 on a singular referent is a hermeneutical innovation serving his argument about faith and Torah rather than a recovery of the original sense. Scholars in this tradition note that the source text ties the blessing to Abraham's own action, whereas Paul redirects it to the identity of a future individual. They regard the reading as creative interpretation detached from the original authorial intent.
The fulfillment reading
How this passage is read as pointing to the Messiah.
On the messianic-fulfillment reading, the repeated narrowing of the blessing-to-the-nations promise through a single chosen line points to one individual descendant through whom the blessing is finally mediated, which Paul at Galatians 3:16 identifies as Christ by pressing the singular 'offspring.' In this view Abraham's obedience in the binding of Isaac is itself typological, foreshadowing the greater obedience of Christ, so the link between obedience and blessing is carried forward rather than severed. Interpreters in this tradition see the New Testament writers as drawing out a christological trajectory already present in the patriarchal promises. The universal scope of the blessing is read as realized in the gospel reaching the nations.
