Verse 1 The writer now proceeds to compare Christ, as the executive head of the new dispensation, with Moses, as that of the old. An apostle is one sent to execute a commission. Christ was commissioned to carry into effect the gospel plan of salvation, as Moses was to establish and maintain the Jewish system of faith and service. Jesus is called the High Priest of the new dispensation, inasmuch as he offered its great sacrifice for sin, in giving up his own life a ransom for men.
