“As touching our brother Apollos, I greatly desired him to come vnto you with þe brethren, but his wil was not at all to come at this time: but he wil come when hee shall haue conuenient time.”
1611 King James Version (KJV)
16:12 I besought him much - To come to you. With the brethren - Who were then going to Corinth. Yet he was by no means willing to come now - Perhaps lest his coming should increase the divisions among them.
1Co 16:12 As touching [our] brother Apollos. Apollos was then at Ephesus when Paul wrote. I greatly desired him to come to you with the brethren. Possibly with Timothy and Erastus. See PNT "1Co 16:10". For some reason Apollos was averse to visiting Corinth at that time.
