Jonah 3:7-9

7And he caused it to be proclaimed and published throughout Nineveh by the decree of the king and his nobles, saying, Let neither man nor beast, herd nor flock, taste anything; do not let them eat, or drink water.

8But let man and beast be covered with sackcloth, and cry mightily to God; yes, let every one turn from his evil way and from the violence that is in his hands.

9Who can tell if God will turn and relent, and turn away from His fierce anger, so that we may not perish?
