Hebrews 7
17 For it is declared: “You are a priest forever, in the order of Melchizedek.” 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 and will not change his mind: ‘You are a priest forever.`” 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.
