Acts 6:4

And they continued stedfastly in the apostles' doctrine and fellowship, and in breaking of bread, and in prayers.

Serving the LORD with all humility of mind, and with many tears, and temptations, which befell me by the lying in wait of the Jews: And how I kept back nothing that was profitable unto you, but have shewed you, and have taught you publickly, and from house to house, Testifying both to the Jews, and also to the Greeks, repentance toward God, and faith toward our Lord Jesus Christ. And now, behold, I go bound in the spirit unto Jerusalem, not knowing the things that shall befall me there: Save that the Holy Ghost witnesseth in every city, saying that bonds and afflictions abide me. But none of these things move me, neither count I my life dear unto myself, so that I might finish my course with joy, and the ministry, which I have received of the Lord Jesus, to testify the gospel of the grace of God. And now, behold, I know that ye all, among whom I have gone preaching the kingdom of God, shall see my face no more. Wherefore I take you to record this day, that I am pure from the blood of all men. For I have not shunned to declare unto you all the counsel of God. Take heed therefore unto yourselves, and to all the flock, over the which the Holy Ghost hath made you overseers, to feed the church of God, which he hath purchased with his own blood. For I know this, that after my departing shall grievous wolves enter in among you, not sparing the flock. Also of your own selves shall men arise, speaking perverse things, to draw away disciples after them. Therefore watch, and remember, that by the space of three years I ceased not to warn every one night and day with tears.

Having then gifts differing according to the grace that is given to us, whether prophecy, let us prophesy according to the proportion of faith; Or ministry, let us wait on our ministering: or he that teacheth, on teaching; Or he that exhorteth, on exhortation: he that giveth, let him do it with simplicity; he that ruleth, with diligence; he that sheweth mercy, with cheerfulness.

For though I preach the gospel, I have nothing to glory of: for necessity is laid upon me; yea, woe is unto me, if I preach not the gospel!

And say to Archippus, Take heed to the ministry which thou hast received in the Lord, that thou fulfil it.

Till I come, give attendance to reading, to exhortation, to doctrine. Neglect not the gift that is in thee, which was given thee by prophecy, with the laying on of the hands of the presbytery. Meditate upon these things; give thyself wholly to them; that thy profiting may appear to all. Take heed unto thyself, and unto the doctrine; continue in them: for in doing this thou shalt both save thyself, and them that hear thee.

Preach the word; be instant in season, out of season; reprove, rebuke, exhort with all longsuffering and doctrine.
