Matthew 22:32

Ἐγώ εἰμι, etc., quoted from Exodus 3:6. The stress does not lie on εἰμι, to which there is nothing corresponding in the Hebrew, bat on the relation implied in the title: God of Abraham. Note in this connection the repetition of the Divine name before each of the patriarchal names, and here the article ὁ before θεὸς each time (not so in Sept [126]). The idea is that the Eternal could not stand in such intimate connection with the merely temporal. The argument holds a fortiori in reference to Christ's name for God, Father, which compels belief in human immortality, and in the immortality of all, for God is Father of all men, whereas the text quoted might avail in proof only of the immortality of the great ones, the heroes of the race. οὐκ ἔστιν ὁ θεὸς, with the article θεὸς is subject, and the idea: God does not belong to the dead; without, it would be predicate = He is not a God of the dead. On second θεὸς vide critical notes.

[126] Septuagint.
