Hebrews 7:17-28 New International Version (NIV)
17 For it is declared:
“You are a priest forever,
18 The former regulation is set aside because it was weak and useless 19 (for the law made nothing perfect), and a better hope is introduced, by which we draw near to God.
20 And it was not without an oath! Others became priests without any oath, 21 but he became a priest with an oath when God said to him:
“The Lord has sworn
22 Because of this oath, Jesus has become the guarantor of a better covenant.
23 Now there have been many of those priests, since death prevented them from continuing in office; 24 but because Jesus lives forever, he has a permanent priesthood. 25 Therefore he is able to save completely[c] those who come to God through him, because he always lives to intercede for them.
26 Such a high priest truly meets our need—one who is holy, blameless, pure, set apart from sinners, exalted above the heavens. 27 Unlike the other high priests, he does not need to offer sacrifices day after day, first for his own sins, and then for the sins of the people. He sacrificed for their sins once for all when he offered himself. 28 For the law appoints as high priests men in all their weakness; but the oath, which came after the law, appointed the Son, who has been made perfect forever.
