“Seeing therefore it remaineth that some must enter therein, and they to whom it was first preached entered not in because of unbelief:”
King James Version (KJV)
4:4 For, long after he had rested from his works, he speaks again. #Gen 2:2|.
4:5 In this psalm, of a rest yet to come.
4:7 After so long a time - It was above four hundred years from the time of Moses and Joshua to David. As it was said before - St. Paul here refers to the text he had just cited.
4:8 The rest - All the rest which God had promised.
Heb 4:6 Seeing therefore it remaineth that some must enter therein. Since God has a rest for his people, and it is not made in vain, there must be some who enter therein. They to whom it was first preached entered not because of unbelief. Those to whom it was first offered entered not because of their unbelief. Hence it remaineth to all who, like Joshua and Caleb, have faith (Nu 14:30,38 26:65 32:11,12).
