Ezekiel 33:7-8

“You, human, are the one I have made a watchman for Israel. If you hear a word from my mouth, you must warn them for me. Suppose I say to the wicked: ‘Wicked people, you will surely die,’ but you don’t speak to warn the wicked to stop doing evil. Then they will die because they were sinners, but I will punish you for their deaths.
