Acts 18:24-28 - The Early Ministry Of Apollos
24 Now a certain Jew named Apollos, a native of Alexandria [Egypt] and an effective speaker, who was well-grounded in the [Old Testament] Scriptures, came to Ephesus. 25 He was a man who had learned the way of the Lord, and with spiritual fervor, taught accurately [what he knew] about Jesus, although he knew [and had received] only the immersion [taught and practiced] by John. 26 He began speaking boldly in the synagogue and when Priscilla and Aquila heard him, they invited him to their home and proceeded to explain to him God's way more accurately [than he had known]. 27 And when he desired to travel over into Achaia, he was encouraged [to do so] by the brothers, who wrote to the disciples [in Achaia and urged them] to welcome him. When he arrived [in Achaia] he was a great help to those who had become believers through the unearned favor of God. [Note: An alternate meaning is, "he was a great help, through God's unearned favor on him to those who had become believers"]. 28 For Apollos effectively refuted [the position of] the Jews, publicly proving, by using the [Old Testament] Scriptures, that Jesus was the Christ.
