In 1 Thessalonians 4:9, Paul uses the same rhetorical phrase 'no need to have anything written to you' about brotherly love — a structural parallel in the letter.

Matthew 24:36 states that no one knows the day or hour but the Father — the same truth that underlies Paul's insistence that they already know the times and seasons.

Mark 13:32 echoes the same teaching: no one knows the day or hour, only the Father — a parallel to Paul's statement about not needing further instruction.

Acts 1:7 records Jesus' own words that it is not for them to know times and seasons — a direct parallel to Paul's acknowledgment that they already know.

In 2 Corinthians 9:1, Paul says it is 'superfluous for me to write' about the offering — another instance of the same rhetorical device of claiming no need to write.
