'Warn' in the Bible

Then the Lord spoke to Moses, “Go down, warn the people, so that they do not break through to the Lord to gaze, and many of them perish.

Moses said to the Lord, “The people cannot come up to Mount Sinai, for You warned us, saying, ‘Set bounds about the mountain and consecrate it.’”

Now then, listen to their voice; however, you shall solemnly warn them and tell them of the procedure of the king who will reign over them.”

So the king sent and called for Shimei and said to him, “Did I not make you swear by the Lord and solemnly warn you, saying, ‘You will know for certain that on the day you depart and go anywhere, you shall surely die’? And you said to me, ‘The word which I have heard is good.’

Whenever any dispute comes to you from your brethren who live in their cities, between blood and blood, between law and commandment, statutes and ordinances, you shall warn them so that they may not be guilty before the Lord, and wrath may not come on you and your brethren. Thus you shall do and you will not be guilty.

“Son of man, I have appointed you a watchman to the house of Israel; whenever you hear a word from My mouth, warn them from Me.

When I say to the wicked, ‘You will surely die,’ and you do not warn him or speak out to warn the wicked from his wicked way that he may live, that wicked man shall die in his iniquity, but his blood I will require at your hand.

When I say to the wicked, ‘O wicked man, you will surely die,’ and you do not speak to warn the wicked from his way, that wicked man shall die in his iniquity, but his blood I will require from your hand.

But if you on your part warn a wicked man to turn from his way and he does not turn from his way, he will die in his iniquity, but you have delivered your life.
