Who was Melchizedek?

Melchizedik found in the old testament in the holy book of GenesisThe existence of Melchizedek.
The term is a transliteration of two Hebrew words, melek and tsedeq. He Hebrew melek means king and tsedeq means righteousness."
Paul is clearly saying that Melchizedek, like the Most High God, was without parents. Neither of them had beginning of days nor end of life. The two of them had always lived and there had never been a time that each of them had not lived. Melchizedek had always possessed life inherent. Life was not given to Him, He was not anyone's so.
God Has Anointed You
Every priest taken from among men is ordained to serve on behalf of men in things pertaining to God so that he may offer gifts and sacrifices for sin. No one takes this honor to himself, he must be called of God, as Aaron was (Hebrews 5:1, 4). So also, Christ did not glorify Himself to be made a high priest, but He who said to Him,
"You are My Son, today I have begotten You" said also in another place, "You are a priest forever, after the order [the facsimile] of Melchizedek" (Hebrews 5:5). Melchizedek served as the Priest of the Most High God. Because He had loved righteousness and hated iniquity, God made Him a Son and anointed Him with the oil of gladness above His brethren (Hebrews 1:9). The word translated "anointed" is the Greek chrio which refers to contact between the one being anointed and the one doing the anointing. The Greek word Christos, translated "Christ" is derived from chrio.
