Deuteronomy 10:16

(16) Circumcise . . . your heart.—“For circumcision is that of the heart, in the spirit, and not in the letter” (Romans 2:29). The verse literally runs thus: Circumcise the foreskin of your heart, and ye will harden your neck no more. It is the same line of thought as St. Paul’s (Galatians 5:16) “Walk in the Spirit, and (then) ye will not fulfil the lust of the flesh.”

(17,18) A great God, a mighty, and a terrible . . . he doth execute the judgment of the fatherless and widow.—“Behold (says Rashi) His might! And close beside His might thou mayest find His humility.” It is not otherwise in later passages of Scripture: “He healeth the broken in heart, and bindeth up their wounds. He telleth the number of the stars, and calleth them all by their names.”
