Hebrews 3:1

Wherefore] A new section begins here, in which argument and exhortation are blended. The connexion with the preceding is not quite plain. It may lie in the fact that Christ has been described (Hebrews 2:10) as a Leader of salvation, conducting God's children to glory, suggesting a similar function performed by Moses, the Leader of God's people to the rest of Canaan. Christ is the Apostle and High Priest of the new profession, as Moses was of the old. But all those who set out under the leadership of Moses did not enter into the. promised rest. Hence the warning against unbelief and falling away from the living God (Hebrews 3:12 : cp. Hebrews 2:1). Holy brethren] They are consecrated to God, as Israel was: cp. Exodus 19:6 and see on Exodus 2:11. The heavenly calling] RV 'a heavenly calling,' as distinguished from the calling of Israel to an earthly Canaan. Apostle and High Priest] Christ is both the messenger (cp. Hebrews 1:2) or representative of God to man, and the representative of man before God.
