Psalms 72:17 → Genesis 12:3

Psalm 72:17 declares "In him may all nations be blessed" (יִתְבָּרְכוּ בוֹ, yitbarekhu vo) — an echo of the Abrahamic promise in Genesis 12:3: "all the families of the earth will be blessed through you" (וְנִבְרְכוּ בְךָ, venivrekhu vekha). The two share the verb בָּרַךְ (barakh, "to bless") joined to a universal scope ("all nations/peoples"). That shared vocabulary is common rather than rare, and it does not by itself carry the connection: Jeremiah 4:2 joins the same hitpael of בָּרַךְ to גּוֹיִם (goyim, "the nations") outside the Abrahamic promise set. The weight of this pair is therefore trajectory-importance, not verbal rarity. What makes it load-bearing is the theological move: the psalm transfers the Abrahamic blessing from Abraham personally to the Davidic king, so that the royal line becomes the vehicle through which the promise of universal blessing reaches "all nations." The pair is best classed a probable interpretive allusion resting on common vocabulary rather than a verbal citation — the right register for it: a genuine link in the promise's development, not a quotation.
