He was faithful to Him who appointed Him [Apostle and High Priest], as Moses also was faithful in all God’s house.

For every high priest chosen from among men is appointed [to act] on behalf of men in things relating to God, so that he may offer both gifts and sacrifices for sins.

so that by two unchangeable things [His promise and His oath] in which it is impossible for God to lie, we who have fled [to Him] for refuge would have strong encouragement and indwelling strength to hold tightly to the hope set before us.

Now if perfection [a perfect fellowship between God and the worshiper] had been attained through the Levitical priesthood (for under it the people were given the Law) what further need was there for another and different kind of priest to arise, one in the manner of Melchizedek, rather than one appointed to the order of Aaron?
