'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 he saved himself there, not once nor twice.

Moreover by them is thy servant warned: In keeping them there is great reward.

But if the watchman see the sword come, and blow not the trumpet, and the people be not warned, and 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.
