Expositor's Bible Commentary Commentary Acts 19:22

"And having sent into Macedonia two of them that ministered unto him, Timothy and Erastus, he himself stayed in Asia for a while." — Acts 19:22 (ASV)

Before going to Jerusalem, Paul sent Timothy and Erastus into Macedonia while he remained “in the province of Asia” somewhat longer—which probably means that he stayed on at Ephesus. Luke has not mentioned Timothy since 18:5, but he was with Paul at Ephesus and served during Paul’s Ephesian ministry as his emissary to Corinth (cf. 1 Corinthians 4:17; 16:10–11). This is the first time we hear of Erastus (cf. 2 Timothy 4:20). As for Silas, though Luke speaks of him repeatedly in describing the second missionary journey, he makes no reference to him in the rest of Acts. Another companion of Paul not mentioned by Luke is Titus, who was extensively involved at various times during the Gentile mission (cf. 2 Corinthians 2:13; 7:6, 13–14; 8:6, 16, 23; 12:18; Galatians 2:1, 3; 2 Timothy 4:10; Titus 1:4).
