Gen 17:10 This is my covenant, which ye shall keep, between me and you and thy seed after thee; Every man child among you shall be circumcised. 11 And ye shall circumcise the flesh of your foreskin; and it shall be a token of the covenant betwixt me and you.12 And he that is eight days old shall be circumcised among you..."
This part of the Covenant became baptism for all babies in the New Testament.
