Gen 17:10

17:10 circumcised. By this ritual the organ of procreation was consecrated to God (cf. Lev. 19:23). More importantly, God wanted the heart and ear consecrated to Him (Deut. 10:16; 30:6; Jer. 4:4; 6:10; Ezek. 44:7, 9). Mere circumcision in the flesh is inadequate to please God (17:11–14 notes; Jer. 9:25, 26).
