Tychicus
Tychicus , an Asiatic Christian who, with Trophimus, accompanied the Apostle Paul on a part of his journey from Macedonia to Jerusalem. He is also alluded to have been with Paul in Rome, where the apostle sent him to Ephesus, probably for the purpose of building up and encouraging the church there. In the New Testament, he is mentioned five times (Acts 20:4; Ephesians 6:21; Colossians 4:7; Titus 3:12; 2 Timothy 4:12).
