The Priestly Family of Melchizedek
1 Melchizedek was both king of Salem and priest of God Most High. He was the one who went out and gave Abraham his blessing, when Abraham returned from killing the kings. 2 Then Abraham gave him a tenth of everything he had.
The meaning of the name Melchizedek is “King of Justice.” But since Salem means “peace,” he is also “King of Peace.” 3 We are not told he had a father or mother or ancestors or beginning or end. He is like the Son of God and will be a priest forever.
4 Notice how great Melchizedek was! Our famous ancestor Abraham gave him a tenth of what he had taken from his enemies. 5 The Law teaches that even Abraham's descendants must give a tenth of what they possess. And they are to give this to their own relatives, who are the descendants of Levi and are priests. 6 Although Melchizedek wasn't a descendant of Levi, Abraham gave him a tenth of what he had. Then Melchizedek blessed Abraham, who had been given God's promise. 7 Everyone agrees a person who gives a blessing is greater than the one who receives the blessing.
8 Priests are given a tenth of what people earn. But all priests die, except Melchizedek, and the Scriptures teach that he is alive. 9 Levi's descendants are now the ones who receive a tenth from people. We could even say that when Abraham gave Melchizedek a tenth, Levi also gave him a tenth. 10 This is because Levi was born later into the family of Abraham, who gave a tenth to Melchizedek.
11 Even though the Law of Moses says the priests must be descendants of Levi, those priests cannot make anyone perfect. So there needs to be a priest like Melchizedek, rather than one from the priestly family of Aaron. 12 And when the rules for selecting a priest are changed, the Law must also be changed.
13 The person we are talking about is our Lord, who came from a tribe that had never had anyone to serve as a priest at the altar. 14 Everyone knows he came from the tribe of Judah, and Moses never said priests would come from that tribe.
15 All of this becomes clearer, when someone who is like Melchizedek is appointed to be a priest. 16 That person wasn't appointed because of his ancestors, but because his life can never end. 17 The Scriptures say about him,

“You are a priest forever,
just like Melchizedek.”

18 In this way a weak and useless command was put aside, 19 because the Law cannot make anything perfect. At the same time, we are given a much better hope, and it can bring us close to God.
20-21 God himself made a promise when this priest was appointed. But he did not make a promise like this when the other priests were appointed. The promise he made is,

“I, the Lord, promise that you
will be a priest forever!
And I will never
change my mind!”

22 This means that Jesus guarantees us a better agreement with God. 23 There have been a lot of other priests, and all of them have died. 24 But Jesus will never die, and so he will be a priest forever! 25 He is forever able to save the people he leads to God, because he always lives to speak to God for them.
26 Jesus is the high priest we need. He is holy and innocent and faultless, and not at all like us sinners. Jesus is honored above all beings in heaven, 27 and he is better than any other high priest. Jesus doesn't need to offer sacrifices each day for his own sins and then for the sins of the people. He offered a sacrifice once for all, when he gave himself. 28 The Law appoints priests who have weaknesses. But God's promise, which came later than the Law, appoints his Son. And he is the perfect high priest forever.
The Priest Melchizedek
1 This Melchizedek was king of Salem and a priest of the Most High God. As Abraham was coming back from the battle in which he defeated the four kings, Melchizedek met him and blessed him, 2 and Abraham gave him one tenth of all he had taken. (The first meaning of Melchizedek's name is “King of Righteousness”; and because he was king of Salem, his name also means “King of Peace.”) 3 There is no record of Melchizedek's father or mother or of any of his ancestors; no record of his birth or of his death. He is like the Son of God; he remains a priest forever.
4 You see, then, how great he was. Abraham, our famous ancestor, gave him one tenth of all he got in the battle. 5 And those descendants of Levi who are priests are commanded by the Law to collect one tenth from the people of Israel, that is, from their own people, even though they are also descendants of Abraham. 6 Melchizedek was not descended from Levi, but he collected one tenth from Abraham and blessed him, the man who received God's promises. 7 There is no doubt that the one who blesses is greater than the one who is blessed. 8 In the case of the priests the tenth is collected by men who die; but as for Melchizedek the tenth was collected by one who lives, as the scripture says. 9 And, so to speak, when Abraham paid the tenth, Levi (whose descendants collect the tenth) also paid it. 10 For Levi had not yet been born, but was, so to speak, in the body of his ancestor Abraham when Melchizedek met him.
11 It was on the basis of the levitical priesthood that the Law was given to the people of Israel. Now, if the work of the levitical priests had been perfect, there would have been no need for a different kind of priest to appear, one who is in the priestly order of Melchizedek, not of Aaron. 12 For when the priesthood is changed, there also has to be a change in the law. 13 And our Lord, of whom these things are said, belonged to a different tribe, and no member of his tribe ever served as a priest. 14 It is well known that he was born a member of the tribe of Judah; and Moses did not mention this tribe when he spoke of priests.
Another Priest, like Melchizedek
15 The matter becomes even plainer; a different priest has appeared, who is like Melchizedek. 16 He was made a priest, not by human rules and regulations, but through the power of a life which has no end. 17 For the scripture says, “You will be a priest forever, in the priestly order of Melchizedek.” 18 The old rule, then, is set aside, because it was weak and useless. 19 For the Law of Moses could not make anything perfect. And now a better hope has been provided through which we come near to God.
20 In addition, there is also God's vow. There was no such vow when the others were made priests. 21 But Jesus became a priest by means of a vow when God said to him,
“The Lord has made a solemn promise
and will not take it back:
‘You will be a priest forever.’”
22 This difference, then, also makes Jesus the guarantee of a better covenant.
23 There is another difference: there were many of those other priests, because they died and could not continue their work. 24 But Jesus lives on forever, and his work as priest does not pass on to someone else. 25 And so he is able, now and always, to save those who come to God through him, because he lives forever to plead with God for them.
26 Jesus, then, is the High Priest that meets our needs. He is holy; he has no fault or sin in him; he has been set apart from sinners and raised above the heavens. 27 He is not like other high priests; he does not need to offer sacrifices every day for his own sins first and then for the sins of the people. He offered one sacrifice, once and for all, when he offered himself. 28 The Law of Moses appoints men who are imperfect to be high priests; but God's promise made with the vow, which came later than the Law, appoints the Son, who has been made perfect forever.
