A.T. Robertson Commentary Hebrews 7:4

"Now consider how great this man was, unto whom Abraham, the patriarch, gave a tenth out of the chief spoils." — Hebrews 7:4 (ASV)

How great (πηλικος). Geometrical magnitude in contrast to arithmetical (ποσος), here only in N.T., "how distinguished." He received tithes from Abraham (verses 4-) and he blessed Abraham and even Levi is included (verses 8-10).

Out of the chief spoils (εκ των ακροθινιων). Old word from ακρος, top, and θις, a heap (the top of the pile).

Patriarch (πατριαρχης). LXX word (πατρια, tribe, αρχω, to rule) transferred to N.T. (Acts 2:29).
