Open your Bible to Hebrews 7
11 So if perfection was through the Levitical priesthood (for on the basis of it the people received the Law), what further need was there for another priest to arise according to the order of Melchizedek, and not be designated according to the order of Aaron? 12 For when the priesthood is changed, of necessity there takes place a change of law also. 13 For the one about whom these things are said belongs to another tribe, from which no one has officiated at the altar. 14 For it is evident that our Lord was descended from Judah, a tribe with reference to which Moses said nothing concerning priests. 15 And this is clearer still, if another priest arises according to the likeness of Melchizedek, 16 who has become a priest not on the basis of a law of physical requirement, but according to the power of an indestructible life. 17 For it is attested of Him,
“You are a priest forever
According to the order of Melchizedek.”
18 For, on the one hand, there is the nullification of a former commandment because of its weakness and uselessness 19 (for the Law made nothing perfect); on the other hand, there is the introduction of a better hope, through which we come near to God. 20 And to the extent that it was not without an oath 21 (for they indeed became priests without an oath, but He with an oath through the One who said to Him,
“The Lord has sworn
And will not change His mind,
‘You are a priest forever’”);
22 by the same extent Jesus also has become the guarantee of a better covenant.
23 The former priests, on the one hand, existed in greater numbers because they were prevented by death from continuing; 24 Jesus, on the other hand, because He continues forever, holds His priesthood permanently. 25 Therefore He is also able to save forever those who come to God through Him, since He always lives to make intercession for them.
26 For it was fitting for us to have such a high priest, holy, innocent, undefiled, separated from sinners, and exalted above the heavens; 27 who has no daily need, like those high priests, to offer up sacrifices, first for His own sins and then for the sins of the people, because He did this once for all time when He offered up Himself. 28 For the Law appoints men as high priests who are weak, but the word of the oath, which came after the Law, appoints a Son, who has been made perfect forever.
