'Warning' in the Bible

To whom shall I speak and give warningThat they may hear?Behold, their ears are closedAnd they cannot listen.Behold, the word of the Lord has become a reproach to them;They have no delight in it.

For I solemnly warned your fathers in the day that I brought them up from the land of Egypt, even to this day, warning persistently, saying, “Listen to My voice.”
