Some early manuscripts containing the text of this chapter are: The further aspect of Jesus' priesthood is introduced here and will be explored in the next chapters, that is, Jesus' role as a "guarantor" ("surety"; Greek: ἔγγυος, engyos[15]) of a better covenant,[a] superior to the old covenant as much as his priesthood is superior to that of Aaron.

[21] Therefore, it becomes a custom for the high priest to first offer sacrifices on his own account, before performing his task for the people, as also attested by the first-century Jewish writer, Philo.

[21] The 'new and perpetual priesthood after Melchizedek's order', given under oath by the Divine acclamation, was designed to supersede the previous priesthood under the ancient law, which was beset by frailty and required sin offerings for the high priest as well as the people.

[23] The supersession became effective once the Messiah ("the Son") 'vindicated his high-priestly title on the basis of a perfect sacrifice', so his 'high-priesthood is absolutely efficacious and eternally suited to meet the need of his people'.
