Galatians 5:6 directly contrasts by saying circumcision has no value in Christ — only faith expressing itself through love matters.

Galatians 3:10 directly supports this: those under the law must keep it all or be cursed. Parallel teaching.

Deuteronomy 27:26 is the OT law Paul quotes in Gal 3:10 — the curse for not keeping all the law.

James 2:10 states the same principle: breaking one part makes you guilty of all — key parallel to Paul's argument.

James 2:11 reinforces that breaking one part of the law makes you guilty of all — exactly the obligation to the whole law Paul describes here.

Acts 13:39 declares justification through Christ that the law could not provide — contrasting Paul's warning that circumcision brings law-obligation.

Romans 2:25 states circumcision is only valuable if you keep the whole law — identical logic to Paul's point here about obligation.

Genesis 17:10 is the original institution of circumcision as covenant sign — the very practice Paul warns obligates one to the entire law.

Leviticus 12:3 commands circumcision on the eighth day as part of the Mosaic law — the law Paul says circumcision binds you to keep fully.

Romans 9:31 shows Israel failed to reach righteousness by pursuing the law — reinforcing that law-obligation (as from circumcision) doesn't save.

Romans 10:3 describes seeking to establish one's own righteousness through law — mirroring the mindset Paul confronts in those who rely on circumcision.
