Genesis 17:11 first commands circumcision as a covenant sign — this is the foundational command that Leviticus 12:3 later applies to the eighth day.

Genesis 17:12 already specifies circumcision on the eighth day — Leviticus 12:3 repeats this exact timing.

Luke 1:59 shows John the Baptist circumcised on the eighth day — demonstrating continued obedience to this command.

Luke 2:21 records Jesus' circumcision on the eighth day — fulfilling the law's requirement from this verse.

John 7:22 references the eighth-day circumcision rule to argue that it overrides Sabbath restrictions.

John 7:23 uses the same logic — if eighth-day circumcision is allowed on Sabbath, healing on Sabbath is also lawful.

Romans 4:11 interprets circumcision as a sign of righteousness by faith — giving deeper meaning to the physical act commanded here.

Romans 4:12 stresses that true circumcision requires faith like Abraham's — the mere physical act is insufficient.

In Colossians 2:11, Paul contrasts physical circumcision (Leviticus 12:3) with spiritual circumcision in Christ.

Acts 15:1 shows this circumcision command being used to demand Gentile converts be circumcised for salvation.
