'Warned' in the Bible

And the king of Israel sent to the place which the man of God told him and warned him of, and saved himself there, not once nor twice.

Moreover by them is thy servant warned: and in keeping of them there is great reward.

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

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.
