1 Corinthians 16:12

But as touching Apollos the brother, I besought him much to come unto you with the brethren: and it was not at all his will to come now; but he will come when he shall have opportunity.

This verse is significant in showing that Paul and Apollos were on friendly terms with each other and that neither Paul nor Apollos was in any manner responsible for the ugly factions that had grown up around their names at Corinth. Paul's desire that Apollos should go to Corinth might have been prompted by the thought that he could give valuable aid in correcting the Corinthian disorders. Also, as some believe, it is possible that communications to Paul from Corinth had requested Apollos to come. Despite their love and affection for each other, however, Apollos was not a pupil of Paul's and felt justified in denying the apostle's request, but promising to go later.
