John Calvin Commentary Hebrews 11:10

"for he looked for the city which hath the foundations, whose builder and maker is God." — Hebrews 11:10 (ASV)

For he looked for, etc. He gives a reason why he ascribes their patience to faith: because they looked forward to heaven. This was indeed to see things invisible. It was no doubt a great thing to cherish in their hearts the assurance God gave them concerning the possession of the land until, after some ages, it was realized. Yet, because they did not confine their thoughts, not even to that land, but penetrated even into heaven, it was still a clearer evidence of their faith.

He calls heaven a city that has foundations, because of its perpetuity; for in the world there is nothing except what is transitory and fading. It may indeed appear strange that he makes God the Maker of heavens as though he did not also create the earth. To this I answer that, just as in earthly buildings the hands of men make use of materials, so the workmanship of God is fittingly contrasted with them. Now, whatever is formed by men is like its authors in instability; so also is the perpetuity of the heavenly life, for it corresponds with the nature of God, its founder. Moreover, the Apostle teaches us that all weariness is relieved by expectation, so that we ought never to be weary in following God.
