Selecting elders {older ones} for them according to the ekklesia/edah/cahal, with prayer with fasting, they commended them to the Lord in whom they had believed.
Acts 14:23

Be on guard for yourselves, and for the entire flock of God, among whom the Spirit has made you overseers, to be shepherding the ekklesia/edah of God, which He purchased with His own blood.
Acts 20:28

A shepherd-overseer must be above reproach, the husband of one wife, having children who believe, temperate, prudent, sensible, just, devout, self-controlled and not self-willed, respectable, not accused of dissipation or rebellion, hospitable, able to teach, not addicted to wine, not pugnacious; but gentle, uncontentious, loving what is good, free from the love of money, holding fast the faithful word which is in accordance with the teaching, that he may be able to both exhort in sound doctrine and to refute those who contradict. (For there are many rebellious men, empty talkers and deceivers, especially those of the circumcision, who must be silenced because they are upsetting whole families, teaching things they should not teach, for the sake of sordid gain.) He must be one who manages his own household well, keeping his children under control with all dignity (if a man does not know to manage his own household, how will he be ready to take care for the church of God?); and not a new convert, lest he become conceited and fall into the condemnation incurred by the devil. And he must have a good reputation with those outside the church, so that he may not fall into reproach and the snare of the devil. Servants likewise must be men of dignity, not double-tongued, or addicted to much wine or fond of sordid gain, but holding to the mystery of the faith with a clear conscience. And let these also first be tested; then let them serve as servants of they are beyond reproach.
from Timothy & Titus

Shepherd the flock of God among you, not of/under compulsion, but voluntarily, according to the will of God; and not avariciously, but eagerly; not as lording over the allotment, but becoming models for/examples to the flock.
I Peter 5:2-3

Shepherd at Herrnhut

Count Zinzendorf’s shepherding included care for the sick. When exercising this type of care, his first step was to inquire concerning the cause of the sickness. His intent was not merely to determine the physical source of the problem, but to discover the Lord’s intention in allowing the sickness. Zinzendorf knew the heavenly Father was watching over all of His children -– the very hairs of their heads are numbered; none becomes ill unless He allows it. The Count believed that when the sick one discerned the reason for the Lord’s chastisement and heartily acknowledged it, he was on his way to recovery, unless he had sinned in such a way that the Lord would rather remove him than leave him on earth in his state. However, if the illness appeared to stem from natural causes alone, Zinzendorf felt that personal care for the individual was at least as important as medicine, and therefore encouraged the brothers and sisters to care for the believers in their sicknesses.
