'Sinned Against the Lord' in the Bible

Then you answered and said to me, "We have sinned against the LORD, we will go up and fight, according to all that the LORD our God commanded us." Every man of you put on his weapons of war, and presumed to go up into the hill country.

I looked, and behold, you had sinned against the LORD your God; you had made yourselves a molten calf: you had turned aside quickly out of the way which the LORD had commanded you.
