So no one should boast about men. For it all belongs to you??22 Paul, Apollos, Cephas, the world, life, death, the present, the future??ll of it belongs to you.

Whether Paul, or Apollos, or Cephas, or the world, or life, or death, or things present, or things to come; all are yours;

Have we not power to lead about a sister, a wife, as well as other apostles, and as the brethren of the Lord, and Cephas?

according to the scriptures, And that he was buried, and that he was raised the third day according to the scriptures: And that he was seen by Cephas, then by the twelve.

and that he was seen of Cephas, then of the twelve.
