New Defender's Study Bible Notes
4:8 Jesus. Most expositors understand this to mean “Joshua,” since “Jesus” is a Greek form of “Joshua,” who is otherwise never mentioned by name in the New Testament. It is also possible to understand this as actually referring to the Lord Jesus Christ, who before His incarnation may have been revealed as “the angel of His presence” (Isaiah 63:9). “In His love and in His pity, He redeemed them,” as He led them into the promised land under Joshua. In any case, this was not the ultimate “rest” God had promised His people, as the next verses show.
