Matthew 23:3 condemns those who say but do not do — directly mirrors the second son who promised obedience but failed to act.

Ezekiel 33:31 describes people hearing God's words but not doing them — exactly the second son's empty promise.

Romans 2:17-25 rebukes those who boast in the law but break it — a strong parallel to the second son's saying without doing.

Titus 1:16 condemns those who profess to know God but deny him by deeds — same hypocrisy as the second son.
