Hebrews 7:1-3

For this Melchizedek, king of Salem, priest of the Most High God, met Abraham as he returned from the slaughter of the kings and blessed him, and Abraham gave him a tenth of all [the spoil]. He is, first of all, by the translation of his name, king of righteousness, and then he is also king of Salem, which means king of peace. Without [any record of] father or mother, nor ancestral line, without [any record of] beginning of days (birth) nor ending of life (death), but having been made like the Son of God, he remains a priest without interruption and without successor.
