God's Priesthoods, Briefly:

The priesthoods, in brief:

Melchizedek (Melchisedec): King of Salem (Peace, Shalom), priest of the most high God Jehovah. 

Abraham paid tithes to Melchizedek; therefore, the Levite priests did not pay tithes, for Levi was yet in the loins of Abraham His father, when Abraham met Melchizedek, but the Levite priests paid tithes out of those tithes gathered from the people, for they were paid, by transduction, to Melchizedek by Abraham.

And Melchizedek blessed Abram (his Hebrew Gentile name, for at this time, there were no Jews; that came with the covenant of 'circumcision'; and Abram was later called 'Abraham', for God would make him a father of many nations. (Ref: Genesis 17:4-5; Galatians 3:6-7). 

In Hebrews, chapters 7 through 10, you will find much information regarding the priesthoods, the tabernacle, sacrifices, and the old covenant (Old Testament), and the new covenant (New Testament).

And Jesus, the Christ, the Messiah, is the 'Anointed' of God, for in Psalm 110:4, God said, 'Thou art a priest for ever after the order of Melchizedek.’

All other priests were anointed by men, and the priesthood of Aaron, the first high priest, Moses' brother, was passed from father to son.

There was a written 'Torah' (Old Testament), and there was an unwritten 'Torah', which only the high priest knew, and that was only spoken, from father (high priest) to son (next high priest).

But our high priest, Jesus, Which is referred to as 'Christ', or 'Messiah' also, is for ever, for He was anointed by His Father, Who gave Jesus the words which He spoke to the Jews, including specifically, the apostles, with the other disciples which followed Jesus:
John 14:23-24: 'Jesus answered and said unto him (Judas, not 'Iscariot'), 'If a man love Me, he will keep My words: and My Father will love him, and We will come unto him, and make Our abode with him. He that loveth Me not keepeth not My sayings: and the word which ye hear is not Mine, but the Father's Which sent Me.'

Deuteronomy 18:18-19: (God speaks with Moses) 'I will raise them (the Jews, Israel, the 'circumcision') up a Prophet from among (not 'of') their brethren, like unto thee, and will put My words in His mouth; and He shall speak unto them (the Jews only, except in a rare case) all that I shall command Him. And it shall come to pass, that whosoever will not hearken unto (hear and obey) My words which He shall speak in My name, I will require it of him (that doth not hearken to them).'

Jesus was not 'of' the sinful flesh of Adam, but God, by the Holy Ghost, was the father of His flesh, and that flesh was sinless, 'made of a woman, made under the law', and not therefore not worthy of death, for death is the penalty of sin, which Christ Jesus did not have in His pure flesh, therefore, He had no sentence pronounced upon His flesh:  

Ref.: Galatians 4:4; Matthew 1:18; Hebrews 10:1-5; Romans 5:12; Hebrews 9:27).

God bless you as you study His thoughts and His ways: Isaiah 55:8-11.
