For Melchizedek, the king of Salem, a priest of the Most High God, who met Abraham on his return from the slaughter of the kings and blessed him ??2 who had a tenth part of everything assigned him by Abraham ??this Melchizedek is primarily a king of righteousness (that is the meaning of his name); then, besides that, king of Salem (which means, king of peace).

but he who had no Levitical genealogy actually tithed Abraham and blessed the possessor of the promises!

(And there is no question that it is the inferior who is blessed by the superior.)

It was by faith that Isaac blessed Jacob and Esau in connexion with the future.

It was by faith that, when Jacob was dying, he blessed each of the sons of Joseph, bending in prayer over the head of his staff.
