1 Corinthians 15:7 - Coke's Commentary on the Holy Bible

Then of all the Apostles.— The change of phrase from that in the conclusion of the 5th verse, is very remarkable, and probably intimates, that they who were there called the twelve, (that is, the greatest part of the company who used to be so denominated) were not, even the whole eleven. On which circumstance a probable conjecture is grounded, that James might, by some accident, have been detained from meeting his brethren, both on the day of the resurrection and that day se'nnight; and likewise at the time when Christ appeared to the five hundred: and that he might in this respect be upon a level with them, our Lord appeared to him alone, after all the appearances mentioned before.
