'Sight' in the Bible

By doing this, the sin of the young men was very serious in the LORD's sight because the men despised the LORD's offering.

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."

Why didn't you obey the LORD, but grabbed the spoil and did evil in the LORD's sight?"
