And when he had spoken this, he saith unto him, Follow me. ²⁰ Then Peter, turning about, seeth the disciple whom Jesus loved following; which also leaned on his breast at supper, and said, Lord, which is he that betrayeth thee? ²¹ Peter seeing him saith to Jesus, Lord, and what shall this man do? ²² Jesus saith unto him, If I will that he tarry till I come, what is that to thee? follow thou me. ²³ Then went this saying abroad among the brethren, that that disciple should not die: yet Jesus said not unto him, He shall not die; but, If I will that he tarry till I come, what is that to thee?
