'Sin Against the Lord' in the Bible

If one man sin against another, the judge shall judge him: but if a man sin against the LORD, who shall intreat for him? Notwithstanding they hearkened not unto the voice of their father, because the LORD would slay them.

Moreover as for me, God forbid that I should sin against the LORD in ceasing to pray for you: but I will teach you the good and the right way:

Then they told Saul, saying, Behold, the people sin against the LORD, in that they eat with the blood. And he said, Ye have transgressed: roll a great stone unto me this day.
