'Sins' in the Bible

If a man sins against a man, one may appeal to God on his behalf. But if a man sins against the Lord, who then will intercede for him?" But Eli's sons would not listen to their father, for the Lord had decided to kill them.

All the people said to Samuel, "Pray to the Lord your God on behalf of us -- your servants -- so we won't die, for we have added to all our sins by asking for a king."
