rwp@1Corinthians:15:6 @{To above five hundred brethren at once} (\epan pentakosiois adelphois ephapax\). \Epan\ here is just an adverb with no effect on the case. As a preposition with the ablative see strkjv@Matthew:5:14|. This incident is the one described in strkjv@Matthew:28:16| the prearranged meeting on the mountain in Galilee. The strength of this witness lies in the fact that the majority (\hoi pleious\) of them were still living when Paul wrote this Epistle, say spring of A.D. 54 or 55, not over 25 years after Christ's resurrection.
