οὐκ ὄντα ἐχαρίσατο, i.e. Isaac. See Rom. iv. 17 , “Before God, in whom he believed, who quickeneth the dead, and calleth those things which be not as though they were” (τὰ μὴ ὄντα ὡς ὄντα); and for the next clause, see ib. ver. 19 , “He considered not his own body, now dead, nor yet the deadness of Sarah’s womb” : to which, so to say, life was restored.
