Acts 13:2

Ministered; the word importeth the exercise of any public office, sacred or civil. But in the former verse mentions being made of prophets and teachers, these words are in sense too conjoined with them; and inform us, that they were preaching to and instructing of the people, (for there is no ministry or service which God likes better than to convert and save souls), and, that all might be more effectual, as being done with greater earnestness and intention of mind, whilst they fasted. The Holy Ghost said; by some inward instinct in those prophets before spoken of, who had warrant to declare it as from him. Separate me Barnabas and Saul; these two were to be separated: as the first born under the law, Exodus 13:12, and after them, or in their stead, the Levites, Numbers 3:12; so were Paul and Barnabas in especial manner separated for the calling in of the Gentiles, that great ministry or service which God had for them to do.
