Hebrews 10:35

Cast not away therefore your confidence, which hath great recompence of reward.

Consequent exhortation to confidence and endurance, as Christ is soon coming.

Cast not away. They now have "confidence," and it will not withdraw of itself, unless they 'cast it away' willfully (cf. Hebrews 3:14).

Which, [ heetis (G3748)] - inasmuch as it.

Hath - present: it is as certain as if you had it in hand (Hebrews 10:37). It hath in reversion.

Recompence of reward - of grace, not debt: of a kind which no mercenary self-seeker would seek: holiness will be its own reward; self-devotion for Christ will be its own rich recompence (note, Hebrews 2:2; Hebrews 11:26).
