2 Samuel 12:5-7 shows David condemning another's sin while guilty of worse — a classic log/speck scenario.

In Psalm 36:2, the wicked flatters himself so he cannot see his own sin — mirroring the beam that blinds self-judgment in this teaching.

Matthew 7:3-5 is the parallel passage — the exact teaching on the speck and log.

In John 8:7, Jesus applies the same principle: only the sinless can judge — reminding us to examine our own sin before condemning others.

Romans 2:1 applies the same principle: judging others condemns yourself because you do the same.

Romans 2:21-24 exposes hypocrisy in teaching — a direct echo of the speck/log warning.

In John 12:5, Judas criticizes Mary's anointing as wasteful yet hides his own greed — a perfect example of the beam/speck hypocrisy.
