If a wild animal killed one of your sheep or goats, I paid for it myself. In fact, you demanded the full price, whether the animal was killed during the day or at night.
I created humans to be like me, and I will punish any animal or person that takes a human life. If an animal kills someone, that animal must die. And if a person takes the life of another, that person must be put to death.
When I tell wicked people they will die because of their sins, you must warn them to turn from their sinful ways so they won't be punished. If you refuse, you are responsible for their death.
Now suppose faithful people start sinning, and I decide to put stumbling blocks in their paths to make them fall. They deserve to die because of their sins. So if you refuse to warn them, I will forget about the times they were faithful, and I will hold you responsible for their death.
But suppose the person watching fails to sound the warning signal. The enemy will attack and kill some of the sinful people in that country, and I, the LORD, will hold that person responsible for their death.
When I tell wicked people they will die because of their sins, you must warn them to turn from their sinful ways. But if you refuse to warn them, you are responsible for their death.
