Charles Ellicott Commentary Acts 18:10

"for I am with thee, and no man shall set on thee to harm thee: for I have much people in this city." — Acts 18:10 (ASV)

For I am with you.—The command was followed by a promise which met the special trial of the time. Men might be against him, but Christ was with him. The general promise given to the Church at large, Lo! I am with you always (Matthew 28:20), received a personal application, I am with you; and though called to a life of suffering, there was for the time an assurance that the wrath of men should be restrained, and that his work should not be hindered.

I have much people in this city.—The words remind us once more of those which Elijah had heard at a moment of like weakness, Yet have I left me seven thousand men in Israel (1 Kings 19:18). Even in the sinful streets of Corinth, among those plunged deepest into its sin (1 Corinthians 5:10–11), there were souls yearning for deliverance, in whom conscience was not dead, and was waiting only for the call to repentance.
