1 Corinthians 16:3

By your letters. Literally, “by letters.” There is some difference of opinion among commentators regarding the writer of the “letters” here mentioned by Paul. The phrase may be linked with either the preceding or the following words. The KJV holds to the former interpretation, as does also the RSV; the other interpretation connects the phrase as follows: “whomsoever ye shall approve, I will send by letters.” Those who hold the former view reason that the letters were written by the leaders of the church at Corinth, and designated the appointment and authority of the bearers as their representatives. Those who hold to the latter interpretation believe that Paul offered to write letters commending the representatives of the Corinthian brethren to the church at Jerusalem. However, no names from Corinth are in the list in Acts 20:4.
