John Wesley on Deuteronomy 33:11

His substance - Because he hath no inheritance of his own and therefore wholly depends upon thy blessing. The work of his hands - All his holy administrations, which he fitly calls the work of his hands, because a great part of the service of the Levites and priests was done by the labour of their hand and body, whereas the service of evangelical ministers is more spiritual and heavenly. Smite - He pray's thus earnestly for them, because he foresaw they who were to teach and reprove, and chastise others would have many enemies, and because they were under God, the great preservers and upholders of religion, and their enemies were the enemies of religion itself.
