1 Corinthians 4:14-16 As my beloved sons I warn you. [15] For though ye have ten thousand instructors in Christ, yet have ye not many fathers: for in Christ Jesus I have begotten you through the gospel. [16] Wherefore I beseech you, be ye followers of me.

Acts 20:27-31 I have not shunned to declare unto you all the counsel of God. [28] Take heed therefore unto yourselves, and to all the flock, over the which the Holy Spirit hath made you overseers, to feed the church of God, which he hath purchased with the blood of his own son. [29] For I know this, that after my departing shall grievous wolves enter in among you, not sparing the flock. [30] Also of your own selves shall men arise, speaking perverse things, to draw away disciples after them. [31] Therefore watch, and remember, that by the space of three years I ceased not to warn every one night and day with tears.

Rom. 16:17 Now I beseech you, brethren, mark them which cause divisions and offences contrary to the doctrine which ye have learned; and avoid them.

Eze 3:17-20 (CEV*) Ezekiel, son of man, I have appointed you as a watchman for the people of Israel. So listen to what I say, then warn them for me. [18] When I tell wicked people they will die because of their sins, you must warn them to turn from their sinful ways so they won't be punished. If you refuse, you are responsible for their death. [19] However, if you do warn them, and they keep on sinning, they will die because of their sins, and you will be innocent. [20] Now suppose faithful people start sinning, and I decide to put stumbling blocks in their paths to make them fall. They deserve to die because of their sins. So if you refuse to warn them, I will forget about the times they were faithful, and I will hold you responsible for their death.

(Eze 33:3-9)� If when he seeth the sword come upon the land, he blow the trumpet, and warn the people; [4] Then whosoever heareth the sound of the trumpet, and taketh not warning; if the sword come, and take him away, his blood shall be upon his own head. [5] He heard the sound of the trumpet, and took not warning; his blood shall be upon him. But he that taketh warning shall deliver his soul. [6] But if the watchman see the sword come, and blow not the trumpet, and the people be not warned; if the sword come, and take any person from among them, he is taken away in his iniquity; but his blood will I require at the watchman's hand.
[7] So thou, O son of man, I have set thee a watchman unto the house of Israel; therefore thou shalt hear the word at my mouth, and warn them from me. [8]� When I say unto the wicked, O wicked man, thou shalt surely die; if thou dost not speak to warn the wicked from his way, that wicked man shall die in his iniquity; but his blood will I require at thine hand. [9]� Nevertheless, if thou warn the wicked of his way to turn from it; if he do not turn from his way, he shall die in his iniquity; but thou hast delivered thy soul.

(1Th 5:14)� Now we exhort you, brethren, warn them that are unruly, comfort the feebleminded, support the weak, be patient toward all men.

(Col 1:28)� Whom we preach, warning every man, and teaching every man in all wisdom; that we may present every man perfect in Christ Jesus:
