'Sins' in the Bible

If a man sins against a man, then God can intercede for him. But if a man sins against Yahweh, who can intercede for him?" But they did not {obey} their father, because Yahweh wanted to kill them.

Then all the people said to Samuel, "Pray for your servants to Yahweh your God so that we will not die, because we have added to all our sins by requesting a king for ourselves."
