'Warn' in the Bible

And whensoever any controversy shall come to you from your brethren that dwell in their cities, between blood and blood, between law and commandment, statutes and ordinances, ye shall warn them, that they be not guilty towards Jehovah, and so wrath come upon you and upon your brethren: this do, and ye shall not be guilty.

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

Yet 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.

Nevertheless if thou warn the righteous man, that the righteous sin not, and he doth not sin, he shall surely live, because he took warning; and thou hast delivered thy soul.

if, when he seeth the sword come upon the land, he blow the trumpet, and warn the people;

When I say unto the wicked, O wicked man, thou shalt surely die, and 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 thy hand.

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

But I will warn you whom ye shall fear: Fear him, who after he hath killed hath power to cast into hell; yea, I say unto you, Fear him.
