circumcision
Circumcision is the "sign" of the Abrahamic Covenant (Genesis 17:7-14); (Romans 4:11). "The reproach of Egypt" was that, during the later years of the Egyptian bondage, this separating sign had been neglected (Compare (Exodus 4:24-26) and this neglect had continued during the wilderness wanderings. The New Testament analogue is world conformity; the failure openly to take a believer's place with Christ in death and resurrection. (Romans 6:2-11); (Galatians 6:14-16). Spiritually it is mortifying the deeds of the body through the Spirit. (Romans 8:13); (Galatians 5:16); (Galatians 5:17); (Colossians 2:11); (Colossians 2:12); (Colossians 3:5-10).
