A.T. Robertson Commentary Hebrews 7:13

"For he of whom these things are said belongeth to another tribe, from which no man hath given attendance at the altar." — Hebrews 7:13 (ASV)

Belongeth to another tribe (φυλης ετερας μετεσχηκεν). See 2:14 for μετεχω, perfect active indicative here. A different (ετερας) tribe.

Hath given attendance at (προσεσχηκεν). Perfect active indicative (watch perfects in Hebrews, not "for" aorists) of προσεχω, old verb, here with either νουν (mind) or self (εαυτον) understood with dative case (τω θυσιαστηριω, the altar, for which word see Mt 5:23; Luke 1:11).
