1 Corinthians 15:3-6 ...
For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures; And that he was buried, and that he rose again the third day according to the scriptures: And that he was seen of Cephas, then of the twelve: After that, he was seen of above five hundred brethren at once;of whom the greater part remain unto this present, but some are fallen asleep.
