Matthew Poole and continuators on Hebrews 10:35

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

This introduceth the last Direction for helping on their Perseverance in Christianity. [non-Latin text not transcribed] denieth all degrees of Apostacy, from secret undervaluing to an utter renouncing, not to slight, despise, or reject; they had endured already so much as might steel and fortifie them against what remained, and implieth the bold, resolute, and couragious Retention, Ephes. 6.10, 16. of the Boldness of their Confession of the Christian Faith. It is an ingenuous, free, bold, and daring Profession of it, which no Brow-beating, nor Violence can dash out of Countenance, the Fruit of a mighty invincible Faith, and hope of eternal Life. This makes them persevere couragiously in their Religion, notwithstanding their being laden with Reproaches and Sufferings for it, as Christ himself gave them a Pattern, Mark 8.31, 32, Acts 4.13, 29, 31.

What greater Incouragement can there be to the retaining this Confidence, than the great Remuneration secured in the New Testament to them. God himself in all his fulness to be their exceeding great Reward seen and enjoyed by them; and which for quality and quantity is unexpressible, Gen. 15.1. Matth. 5.12. and 10.32.
