Yeshua said:

Mark.9 [35] And he sat down, and called the twelve, and saith unto them, If any man desire to be first, the same shall be last of all, and servant of all.

Mark.10[44] And whosoever of you will be the chiefest, shall be servant of all.

Tit.1:5 For this cause left I thee in Crete, that thou shouldest set in order the things that are wanting, and ordain elders in every city, as I had appointed thee:[6] If any be blameless, the husband of one wife, having faithful children not accused of riot or unruly.
[7] For a bishop must be blameless, as the steward of God; not selfwilled, not soon angry, not given to wine, no striker, not given to filthy lucre;
[8] But a lover of hospitality, a lover of good men, sober, just, holy, temperate;
[9] Holding fast the faithful word as he hath been taught, that he may be able by sound doctrine both to exhort and to convince the gainsayers.

Jas.5[14] Is any sick among you? let him call for the elders of the church; and let them pray over him, anointing him with oil in the name of the Lord:

1Pet.5 [1] The elders which 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 thereof, not by constraint, but willingly; not for filthy lucre, but of a ready mind;
[3] Neither as being lords over God's heritage, but being ensamples to the flock.
[4] And when the chief Shepherd shall appear, ye shall receive a crown of glory that fadeth not away.

Phil.1 [1] Paul and Timotheus, the servants of Jesus Christ, to all the saints in Christ Jesus which are at Philippi, with the bishops and deacons:

1Tim.2:[7] Whereunto I am ordained a preacher, and an apostle, (I speak the truth in Christ, and lie not;) a teacher of the Gentiles in faith and verity.8] I will therefore that men pray every where, lifting up holy hands, without wrath and doubting.
[9] In like manner also, that women adorn themselves in modest apparel, with shamefacedness and sobriety; not with broided hair, or gold, or pearls, or costly array;
[10] But (which becometh women professing godliness) with good works.
[11] Let the woman learn in silence with all subjection.
[12] But I suffer not a woman to teach, nor to usurp authority over the man, but to be in silence.
[13] For Adam was first formed, then Eve.
[14] And Adam was not deceived, but the woman being deceived was in the transgression.
[15] Notwithstanding she shall be saved in childbearing, if they continue in faith and charity and holiness with sobriety.

1Tim.3:[1] This is a true saying, If a man desire the office of a bishop, he desireth a good work.
[2] A bishop then must be blameless, the husband of one wife, vigilant, sober, of good behaviour, given to hospitality, apt to teach;
[3] Not given to wine, no striker, not greedy of filthy lucre; but patient, not a brawler, not covetous;
[4] One that ruleth well his own house, having his children in subjection with all gravity;
[5] (For if a man know not how to rule his own house, how shall he take care of the church of God?)
[6] Not a novice, lest being lifted up with pride he fall into the condemnation of the devil.
[7] Moreover he must have a good report of them which are without; lest he fall into reproach and the snare of the devil.
[8] Likewise must the deacons be grave, not doubletongued, not given to much wine, not greedy of filthy lucre;
[9] Holding the mystery of the faith in a pure conscience.
[10] And let these also first be proved; then let them use the office of a deacon, being found blameless.
[11] Even so must their wives be grave, not slanderers, sober, faithful in all things.
[12] Let the deacons be the husbands of one wife, ruling their children and their own houses well.
[13] For they that have used the office of a deacon well purchase to themselves a good degree, and great boldness in the faith which is in Christ Jesus.

Yeshua selected His Apostles first:

Matt.10:[2] Now the names of the twelve apostles are these; The first, Simon, who is called Peter, and Andrew his brother; James the son of Zebedee, and John his brother;[3] Philip, and Bartholomew; Thomas, and Matthew the publican; James the son of Alphaeus, and Lebbaeus, whose surname was Thaddaeus;
[4] Simon the Canaanite, and Judas Iscariot, who also betrayed him.[5] These twelve Jesus sent forth, and commanded them...
1Cor.12 [28] And God hath set some in the church, first apostles, secondarily prophets, thirdly teachers, after that miracles, then gifts of healings, helps, governments, diversities of tongues.

Eph.4:11 And he gave some, apostles; and some, prophets; and some, evangelists; and some, pastors and teachers;

Heb.2:4 God also bearing them witness, both with signs and wonders, and with divers miracles, and gifts of the Holy Ghost, according to his own will?

Eph.48 Wherefore he saith, When he ascended up on high, he led captivity captive, and gave gifts unto men.

1Cor.12:1 Now concerning spiritual gifts, brethren, I would not have you ignorant.[4] Now there are diversities of gifts, but the same Spirit.

[7] But the manifestation of the Spirit is given to every man to profit withal.

[8] For to one is given by the Spirit the word of wisdom; to another the word of knowledge by the same Spirit;

[9] To another faith by the same Spirit; to another the gifts of healing by the same Spirit;

[10] To another the working of miracles; to another prophecy; to another discerning of spirits; to another divers kinds of tongues; to another the interpretation of tongues:

[11] But all these worketh that one and the selfsame Spirit, dividing to every man severally as he will.

1Cor.14:1 Follow after charity, and desire spiritual gifts, but rather that ye may prophesy. [12] Even so ye, forasmuch as ye are zealous of spiritual gifts, seek that ye may excel to the edifying of the church.
