There are no changes from Matthew 7:3–5.
These three verses are an elaboration of the lesson of verses 1 and 2. Verses 1 and 2 simply indicated that we should be careful in the way we judge others. These three verses tell us one of the reasons. There are times when we can be critical of some small problem that we see in someone else, while we are totally oblivious to the larger sin in our own lives. This is another reason that we should “judge not, that [we] be not judged.”
Verses 3–5 teach the same message as the parable of the unforgiving servant (Matthew 18:21–35).
