Hebrews 4:3

He wants to make clear three rests mentioned in the divine Scripture: first, the seventh day, on which God finished creating; second, the land of promise; and third, the kingdom of heaven. He provides proof of this from the inspired testimony: If there is no other rest (he is saying), why on earth does he also urge those in receipt of the second kind not to harden their hearts, threaten punishment and make mention of those who spurned the second kind? He cites them in order, and firstly the rest on the seventh day.

For "we who have believed," he says, "do enter into rest." From what this is evident, he adds: "as He said, as I have sworn in My wrath, if they shall enter into My rest: although the works were finished from the foundation of the world." This indeed, is not evidence that we shall enter in, but that they did not enter in. What then? Thus far he aims to show that as that rest does not hinder the speaking of another rest, so neither does this exclude that of Heaven. Up to this point then, he wishes to show that they the Israelites did not attain to the rest.

The testimony also judges from which it makes that apparent. And see how it establishes that. In any case, he says, it is necessary that some enter into the rest of God, lest the promise be made in vain and rashly. Therefore, since they did not enter (for he swore that they shall not enter), it is necessary for us, as long as we wish, to enter, not now into a figurative rest, but into the true kingdom of heaven. For although their children entered the promised land, now another rest is defined through David. For what else does it mean: "Today, if you hear his voice"? (Heb. 3:15) As I swore in my wrath. But this testimony is not meant for those of us who have believed, who enter into the rest of God, but for those who do not enter: indeed, he says, since they did not enter, we must enter. For he speaks more openly in this progression. Now, indeed, besides this, he wishes to show that just as the rest of the Sabbath does not prevent another rest of the promised land from being called rest, so neither does the rest of the promised land prevent the kingdom of heaven from being called rest. Therefore, he also adds: although his works were finished from the foundation of the world, from which God rested, did not prevent the land of promise from being called rest.
