1 Corinthians 16:12

As touching our brother Apollos. — St. Paul, free from the smallest spark of personal jealousy, had wished that Apollos, whose name had been used as the designation of a faction in opposition to the Apostle himself, should go with this letter to Corinth. St. Paul had planted, Apollos had watered that Church, and in the absence of the planter, Apollos would have been the most likely and proper person to exercise authority there. The unselfish consideration of St. Paul is equalled by the thoughtful reluctance of Apollos, who fears that his presence might encourage the one faction, and perhaps embitter the other, and he declines, not considering it a “convenient” time to do so. In the thought of these teachers “convenient” meant the good of Christ’s Church, and not the ease or comfort of any individual man.
