“For he spake in a certain place of the seventh day on this wise, And God did rest the seventh day from all his works.”
King James Version (KJV)
4:4 For, long after he had rested from his works, he speaks again. #Gen 2:2|.
Heb 4:4 He spake in a certain place. In Ge 2:2. There it is stated that And God did rest the seventh day from all his works. The Sabbath rest was therefore established long before Israel was denied entrance into the rest. Hence it is not "the rest".
