No stranger that was uncircumcised might eat of it. Neither may any now approach the Lord's supper who have not first submitted to baptism; nor shall any partake of the benefit of Christ's sacrifice, who are not first circumcised in heart. Any stranger that was circumcised might eat of the passover, even servants. Here is an indication of favour to the poor Gentiles, that the stranger, if circumcised, stands upon the same level with the home — born Israelite; one law for both. This was a mortification to the Jews, and taught them that it was their dedication to God, not their descent from Abraham, that entitled them to their privileges.
