Acts 19:22

So he sent into Macedonia two of them that ministered unto him, Timotheus and Erastus; but he himself stayed in Asia for a season.

So he sent into Macedonia two of them that ministered unto him, Timotheus and Erastus - as his pioneers, in order (as he tells the Corinthians) to "bring them in remembrance of his ways which were in Christ" (), or, in other words, to communicate his mind to them on various matters. (Compare also .) After a brief stay, he wished Timothy to return to him (). That this Erastus was the same who is called (in ) "the chamberlain of the city" (of Corinth) is very doubtful. He is again mentioned in .

But he himself stayed in (Roman) Asia for a season - meaning, in the province (in contrast with "Macedonia," in the previous clause), and at Ephesus, its capital city.
