Acts 18:9-11

Acts 18:9-11. Then spake the Lord to Paul in the night by a vision, Be not afraid, but speak, and hold not thy peace: For I am with thee, and no man shall set on thee to hurt thee: for I have much people in this city. And he continued there a year and six months, teaching the Word of God among them.

Farmers like to plough good soil, where they expect large harvests. So Paul, who was accustomed to make riving visits to places, on this occasion settled down for a long time - even for a year and a half. It would pay to do it, for God had much people in that city.
