Acts 20:28
Be on guard for yourselves and for all the flock, among which the Holy Spirit has made you overseers, to shepherd the church of God which He purchased with His own blood.
1 Timothy 3:1-7
It is a trustworthy statement: if any man aspires to the office of overseer, it is a fine work he desires to do. 2 An overseer, then, must be above reproach, the husband of one wife, temperate, prudent, respectable, hospitable, able to teach, 3 not addicted to wine or pugnacious, but gentle, peaceable, free from the love of money. 4 He must be one who manages his own household well, keeping his children under control with all dignity 5 (but if a man does not know how to manage his own household, how will he take care of the church of God?), 6 and not a new convert, so that he will not become conceited and fall into the condemnation incurred by the devil. 7 And he must have a good reputation with those outside the church, so that he will not fall into reproach and the snare of the devil.
Titus 1:5-9
For this reason I left you in Crete, that you would set in order what remains and appoint elders in every city as I directed you, 6 namely, if any man is above reproach, the husband of one wife, having children who believe, not accused of dissipation or rebellion. 7 For the overseer must be above reproach as God’s steward, not self-willed, not quick-tempered, not addicted to wine, not pugnacious, not fond of sordid gain, 8 but hospitable, loving what is good, sensible, just, devout, self-controlled, 9 holding fast the faithful word which is in accordance with the teaching, so that he will be able both to exhort in sound doctrine and to refute those who contradict.
1 Peter 5:1-4
Therefore, I exhort the elders among you, as your fellow elder and witness of the sufferings of Christ, and a partaker also of the glory that is to be revealed, 2 shepherd the flock of God among you, exercising oversight not under compulsion, but voluntarily, according to the will of God; and not for sordid gain, but with eagerness; 3 nor yet as lording it over those allotted to your charge, but proving to be examples to the flock. 4 And when the Chief Shepherd appears, you will receive the unfading crown of glory.
