Greek of the New Testament: πρὸς ὃν ἐλαλήθη ὅτι Ἐν Ἰσαὰκ κληθήσεταί σοι σπέρμα
Hebrew (Masoretic text): וַיֹּאמֶר אֱלֹהִים אֶל אַבְרָהָם אַל יֵרַע בְּעֵינֶיךָ עַל הַנַּעַר וְעַל אֲמָתֶךָ כֹּל אֲשֶׁר תֹּאמַר אֵלֶיךָ שָׂרָה שְׁמַע בְּקֹלָהּ כִּי בְיִצְחָק יִקָּרֵא לְךָ זָרַע
Septuagint (Genesis 21:12 in the Septuagint numbering): εἶπεν δὲ ὁ θεὸς τῷ Ἀβραάμ Μὴ σκληρὸν ἴστω τὸ ῥῆμα ἐναντίον σου περὶ τοῦ παιδίου καὶ περὶ τῆς παιδίσκης· πάντα ὅσα ἐἀν εἴπῃ σοι Σάρρα, ἄκουε τῆς φωνῆς αὐτῆς· ὅτι ἐν Ἰσαὰκ κληθήσεταί σοι σπέρμα.
The Greek of the NT matches the Septuagint word for word in 6 consecutive words: “ὅτι Ἐν Ἰσαὰκ κληθήσεταί σοι σπέρμα.”
