1 Peter 5:1-2; 1 Peter 5:5; 1 Peter 5:13

1 The elders who are among you I exhort, who am also an elder and a witness of the sufferings of Christ, and also a partaker of the glory that shall be revealed: 2 feed the flock of God which is among you, taking the oversight of them, not by constraint but willingly, not for filthy lucre but out of a ready mind,
5 Likewise, ye younger, submit yourselves unto the elder. Yea, all of you be subject one to another, and be clothed with humility; for "God resisteth the proud, and giveth grace to the humble."
13 The church that is at Babylon, elected together with you, saluteth you, and so doth Mark, my son.
