“Then spake the Lord to Paul in the night by a vision, Be not afraid, but speak, and hold not thy peace:”
King James Version (KJV)
18:7 He went into the house of one named Justus - A Gentile, and preached there, though probably he still lodged with Aquila.
18:8 And many hearing - The conversation of Crispus, and the preaching of Paul.
18:10 I am with thee: therefore fear not all the learning, politeness, grandeur, or power of the inhabitants of this city. Speak and hold not thy peace - For thy labour shall not be in vain. For I have much people in this city - So he prophetically calls them that afterward believed.
18:11 He continued there a year and six months - A long time! But how few souls are now gained in a longer time than this? Who is in the fault? Generally both teachers and hearers.
Ac 18:9 The spake the Lord to Paul. In some way he manifested his presence and cheered him in his work, by the assurance of great success. We know that the result was not only a flourishing church in Corinth, to which two epistles were written, but churches through Achaia, the province of which Corinth was the capital (2Co 1:1).
