Acts 18:9-11 New King James Version (NKJV)

9 Now the Lord spoke to Paul in the night by a vision, “Do not be afraid, but speak, and do not keep silent; 10 for I am with you, and no one will attack you to hurt you; for I have many people in this city.” 11 And he continued there a year and six months, teaching the word of God among them.
