Heb. 11:38. those of whom the whole world was not worthy,
You cannot, he says, say that they, being sinners, suffered this, but rather such people who are more precious than the world itself. "World" Scripture calls both the multitude of people and creation itself. Here one can understand both meanings. Therefore, he says, if you set against them all of creation together with the people contained in it, you will find nothing equal to them in dignity. Here he stirs their hearts so that they would not care about anything worldly, if the world is not worthy of the saints. It is a disgrace (ύβρις) for you if you receive your reward here. For you have shown that you yourself are worth nothing. If the whole world is not worthy of one saint, then why do you care to have your share in it?
Heb. 11:38. they wandered in deserts and mountains, in caves and crevices of the earth.
They wandered in deserts and mountains, in caves and holes in the ground. For example, Elijah, as well as the prophets whom Obadiah secretly fed in a cave (1 Kings 18:4). They did not even dare to inhabit the wilderness without fear, he says, but were driven from there too by fear, and they moved from one place to another. However, they believed that they would receive eternal consolation from God, and therefore endured this.
Heb. 11:39. And all these, having obtained witness through faith, did not receive what was promised.
Why, he says, are you fainthearted because, being in the struggle, you have not yet received the rewards? All the saints mentioned, although they had already been testified to as having been pleasing through faith, nevertheless had not yet received the heavenly promises. However, some were deemed worthy of earthly promises, like David. But this was not what they sought. That which is in heaven — these are the true promises.
Heb. 11:40. Because God had foreseen something better for us, so that they would not reach perfection without us.
He calls "better" that which pertains to our honor. Lest it seem that they have an advantage over us in being crowned first, God appointed one time of crowning for all. And he did not say: that they should not be crowned without us, but: "that they should not apart from us be made perfect." Therefore it is then that they will be shown to be perfect. But now they possess in general a pledge toward honor. For otherwise, whence comes their power to appear in aid of those who call upon them? Whence comes their boldness to intercede before God? They will receive perfection then. Is God then unjust toward them, if they preceded us in labors yet in receiving crowns they wait for us? On the contrary, this is also desirable for them, namely, to attain perfection together with their brethren. We are all one body; there is more pleasure for the body when it is crowned in its entirety. For God is a child-loving Father, Who has many sons: some of them, having finished their tasks sooner, returned from the fields, while others still remain there, occupied with labors. To those who labored first, He granted a certain foretaste, commanding them to await their brethren for the final banquet; and they, being lovers of mankind, joyfully wait, so that they may delight in the common celebration.
