Study Bible

Generation after generation
This phrase emphasizes the perpetual nature of the covenant God established with Abraham. It signifies that the commandment is not limited to Abraham's immediate descendants but extends to all future generations. This continuity reflects the everlasting covenant God made with Abraham, as seen in Genesis 17:7, and underscores the enduring nature of God's promises.

every male must be circumcised
Circumcision is introduced as a physical sign of the covenant between God and Abraham's descendants. It serves as a mark of identity and belonging to God's chosen people. This practice distinguishes the Israelites from other nations and symbolizes purity and dedication to God. In the New Testament, circumcision becomes a metaphor for spiritual purity and commitment, as seen in Romans 2:29 and Colossians 2:11.

when he is eight days old
The specification of the eighth day for circumcision is significant both medically and theologically. Medically, it is the time when an infant's blood clotting ability is optimal. Theologically, the number eight often symbolizes new beginnings in the Bible, as seen in the resurrection of Jesus on the first day of the new week. This timing underscores the idea of entering into a new covenant relationship with God.

including those born in your household
This phrase indicates that the covenant sign of circumcision is not limited to biological descendants but extends to all males within the household. This inclusivity reflects the broader scope of God's covenant, which encompasses all who are part of the community of faith, similar to the inclusion of Gentiles in the New Testament church as seen in Acts 10.

and those purchased from a foreigner
The inclusion of those purchased from foreigners highlights the universal reach of God's covenant. It suggests that even those who are not originally part of the covenant community can be integrated into it. This foreshadows the New Testament teaching that salvation through Christ is available to all, regardless of ethnic or cultural background, as seen in Galatians 3:28.

even those who are not your offspring
This final phrase reinforces the idea that the covenant sign of circumcision is not restricted to direct descendants. It points to the broader spiritual family that God is forming, which includes all who come under His covenant, prefiguring the New Testament concept of adoption into God's family through faith in Christ, as described in Ephesians 1:5.
