1 Corinthians 11:23; 1 Corinthians 15:1; 1 Corinthians 15:3

23 For I have received of the Lord that which also I delivered unto you, That the Lord Jesus the same night in which he was betrayed took bread:
1 Moreover, brethren, I declare unto you the gospel which I preached unto you, which also ye have received , and wherein ye stand ;
3 For I delivered unto you first of all that which I also received , how that Christ died for our sins according to the scriptures;
