Genesis 18:10 - Exposition

And he said (the Principal Guest, as above, who, by the very nature and terms of his announcement, identifies himself with Jehovah), I will certainly return unto thee according to the time of life. Literally, at the time reviving ; i.e. when the year shall have been renewed, in the next year, or rather spring; though other interpretations of the phrase have been suggested, as, e.g; "according to the time of that which is born," i.e. at the end of nine months (Willet, Calvin, Bush, Murphy). And, lo, Sarah thy wife shall have a son . I .e. at the time specified. And Sarah heard it in the tent door, which was behind him.
