'Warn' in the Bible

And what cause soever comes to you of your brethren that dwell in their cities, between blood and blood, between law and commandment, statutes and ordinances, ye shall even warn them that they trespass not against Jehovah, and so wrath come upon you and upon your brethren: this do and ye shall not trespass.

When I say unto the wicked, Thou shalt certainly die; and thou givest him not warning, nor speakest to warn the wicked from his wicked way, that he may live: the same wicked man shall die in his iniquity; but his blood will I require at thy hand.

But if thou warn the wicked, and he turn not from his wickedness, nor from his wicked way, he shall die in his iniquity; but thou hast delivered thy soul.

And if thou warn the righteous man, that the righteous sin not, and he doth not sin, he shall certainly live, for he hath taken warning; and thou hast delivered thy soul.

if he see the sword coming upon the land, and blow the trumpet, and warn the people;

So thou, son of man, I have set thee a watchman unto the house of Israel; and thou shalt hear the word from my mouth, and warn them from me.

When I say unto the wicked, Wicked man, thou shalt certainly die; and thou speakest not to warn the wicked from his way, that wicked man shall die in his iniquity; but his blood will I require at thy hand.

But if thou warn the wicked of his way to turn from it, and he do not turn from his way, he shall die in his iniquity; but thou hast delivered thy soul.
