3 Without father, without mother, without genealogy, he has neither beginning of days nor end of life but is like the son of God, and he remains a priest for all time.

Darby

3 without father, without mother, without genealogy; having neither beginning of days nor end of life, but assimilated^D9047 to the Son of God, abides a priest continually^D9048.

Darby Bible Notes

assimilated - Melchisedec was in his characteristics assimilated to the Son of God. 'Abides' is in direct connection with 'this Melchisedec,' ver. 1. continually - 'In perpetuity,' not as ch. 6.20. see ch. 5.6.

KJV
