Genesis 14:18
And Melchizedek king of Salem brought out bread and wine ; now he was a priest of God Most High.
Hebrews 7:11
Now 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 ?In the Old Testament God made sure that no priest of Israel would ever become a king He also made sure that no king would ever become a priest. How did He do this, well we have Genesis 49:10 and we have Exodus 28:1. However there is the order of priesthood that can be king and high priest and that is the order that Christ belongs to 'Melchizedek'. Our text tells us that Melchizedek was in fact the king of Salem, which is today Jerusalem. Now you ask why is this important, well there's two things to consider one Christ is to be king of Israel to set on David's throne and He also is the high priest the Most High-Priest, thirdly he holds the office of prophet, which either a king or a priest could hold. The other problem is with the lineage of the Levites is they could not minister or be priest of Gentiles because gentiles do not believe or follow the law this would mean if the Messiah came from the lineage of the Levites He could only die for salvation for the Jews and not the Gentiles. It was important that Christ be sacrificed for all nations, all men, and this was the way that it had to be done. Just remember that if he was a Levite he would be commanded to receive tie from people according to law and that would limit the value of His blood.
