Homilies on the Epistle to the Hebrews

^2. “By faith Abraham when he was called to go out into a place which he should after receive for an inheritance, obeyed; and he went out not knowing whither he went. By faith he sojourned in the land of promise, as in a strange country, dwelling in tabernacles, with Isaac and Jacob, the heirs with him of the same promise.” [“By faith”]: for (tell me) whom did he see to emulate? He had for father a Gentile, and an idolater; he had heard no prophets; he knew not whither he was going. For as they of the Hebrews who believed, looked to these [patriarchs] as having enjoyed blessings innumerable, he shows that none of them obtained anything as yet; all are unrewarded; no one as yet received his reward. “He” escaped from his country and his home, and “went out not knowing whither he went.”

And what marvel, if he himself [were so], when his seed also dwelt in this same way? For seeing the promise disproved (since He had said, “To you will I give this land, and to your seed”), he saw his son dwelling there; and again his grandson saw himself dwelling in a land not his own; yet was he nowise troubled. For the affairs of Abraham happened as we might have expected, since the promise was to be accomplished afterwards in his family (although it is said even to himself, “To you, and to your seed,” not, “to you through your seed,” but “to you and to your seed”): still neither he, nor Isaac, nor Jacob, enjoyed the promise. For one of them served for hire, and the other was driven out: and he himself even was failing through fear: and while he took some things indeed in war, others, unless he had had the aid of God, would have been destroyed. On this account [the Apostle] says, “with the heirs of the same promise”; not himself alone, he means; but the heirs also.
