In 4:21, Paul urgently asks Timothy to come before winter — another personal request showing his pressing circumstances.

2 Corinthians 11:27 mentions Paul being in cold and nakedness, directly parallel to his request for a cloak against the cold.

Acts 20:5-12 narrates Paul's stay in Troas, where he raised Eutychus; this is the visit when he likely left his cloak.

Acts 20:6 records Paul's visit to Troas, likely when he left his cloak there — explaining the context of Paul's request.
