▼ Heb “circumcise the foreskin of” (cf. KJV, ASV, NRSV). Reference to the Abrahamic covenant prompts Moses to recall the sign of that covenant, namely, physical circumcision (Gen 17:9–14). Just as that act signified total covenant obedience, so spiritual circumcision (cleansing of the heart) signifies more internally a commitment to be pliable and obedient to the will of God (cf. Deut 30:6; Jer 4:4; 9:26).

▼ Heb “your neck do not harden again.” See note on the word “stubborn” in Deut 9:6.
