'Evil in the Sight of the Lord' in the Bible

I fell down in the LORD's presence, just as I had the first 40 days and nights. I did not eat food or drink water because of your sin. You had sinned by committing this evil in the sight of the LORD, thereby provoking him to anger.

Is it not the wheat harvest today? I'll call upon the LORD, and he will send thunder and rain. Then you will know and understand that you have done a great evil in the sight of the LORD by asking for a king for yourselves."
