1 Corinthians 16:10-12

ISV(i) 10 If Timothy comes, see to it that he does not have anything to be afraid of while he is with you, for he is doing the Lord’s work as I am. 11 Therefore, no one should treat him with contempt. Send him on his way in peace so that he may come to me, because I am expecting him along with the brothers.
12 Now concerning our brother Apollos, I strongly urged him to visit you with the other brothers, but he was not inclined to do so just now. However, he will visit you when the time is right.
