Note 3 at Ac 20:4: The name Sopater means "of a safe father" (Strong's Concordance). This man was one of Paul's converts in Berea (see note 1 at Ac 17:10) during his second missionary journey (see note 1 at Ac 18:22). This verse reveals that during Paul's third missionary journey, Sopater accompanied Paul into Asia (see note 3 at Ac 16:6). Some speculate that the Sosipater of Ro 16:21 is the same man, but there is no scriptural evidence for or against that.

Note 4 at Ac 20:4: This is the only mention of Secundus in Scripture. The name means "second" (Strong's Concordance).

Note 5 at Ac 20:4: This is not the same Gaius who was from Macedonia and was mentioned in Ac 19:29 (see note 4 at Ac 19:29).

Note 6 at Ac 20:4: Tychicus is mentioned five times in Scripture (Ac 20:4, Eph 6:21, Col 4:7, 2Ti 4:12, and Tit 3:12) and twice in subscripts (Eph 6:24 and Col 4:18).

Tychicus was a Christian from Asia (see note 3 at Ac 16:6) who accompanied Paul on his travels. He is first mentioned in Scripture here in Ac 20:4 as going in advance of Paul with others from Macedonia (see note 1 at Ac 16:9) unto Troas (Ac 20:5, see note 7 at Ac 16:8) of Asia during Paul's third missionary journey.

Paul called Tychicus "a beloved brother and faithful minister in the Lord" in Eph 6:21. Tychicus was with Paul during his imprisonment in Rome, as can be seen by Tychicus being the bearer of two of Paul's epistles that were written from Rome (Eph 6:21 and Col 4:7), and had an intimate knowledge of all of Paul's affairs. Paul also sent Tychicus from Rome to Ephesus (2Ti 4:12) and spoke of sending Tychicus or Artemas to Titus in Crete (Tit 3:12, see note 18 at Ac 2:11).

Note 7 at Ac 20:4: Trophimus was a Christian of Ephesus (Ac 21:29, see note 3 at Ac 18:19) who accompanied Paul on his third missionary journey. Paul left Trophimus at the seaport of Miletum, sick (2Ti 4:20). However, Trophimus must not have remained sick very long since he was in Jerusalem at the same time Paul was there, and Paul was falsely accused of having brought Trophimus into the temple (Ac 21:29).
