Circumcise yourselves to the Lord. A significant passage. All the Jews were circumcised, but not all were "circumcised to the Lord." There were but too many who were "circumcised in uncircumcision" (Jeremiah 9:25), and the prophet sternly reduces ouch circumcision to the level of the heathenish rite of cutting off the hair (Jeremiah 9:26; comp.
Herod. 3.8). Jeremiah seems to have been specially anxious to counteract a merely formal, ritualistic notion of circumcision, sharing in this, as in other points, the influence of the Book of Deuteronomy, so lately found in the temple (comp.
Deuteronomy 10:16). To him the venerable rite of circumcision (older, certainly, than Abraham) is a symbol of the devotion of the heart to its rightful Lord (comp. St. Paul in Romans 2:28, Romans 2:29; Colossians 2:11; Philippians 3:3).
