Genesis 3:20
"And Adam called the name of his wife Life, because she was the mother of all living."
If Eve is the mother of all living, what about Melchizedek?
If Eve is the "mother of all living" then what of Melchizedek, who is described as "without mother"?
A point to begin is that "living" in Hebrew carries the meaning of fleshly life. Then we need to know that Melchizedek was regarded by some second-temple Jewish groups as a heavenly being, and that Hebrews utilizes themes surrounding his unique priesthood. Therefore Melchizedek's typological description as "without mother" does not categorize him under the fleshly descent delineated in Gen. 3:20.
