'Eyes' in the Bible

"If the whole congregation of Israel goes astray, and if the sin is hidden from the eyes of the assembly, and if they go astray from one of the LORD's commands that should not be violated, then they will stand guilty.

then I will certainly do this to you: I'll appoint sudden terror to infect you like tuberculosis and fever. Your eyes will fail and your life will waste away. You'll plant in vain, because your enemies will consume what you plant.

Instead, on account of them, I'll remember my covenant with their ancestors when I brought them out of the land of Egypt right before the eyes of the nations, so that I could be their God. I am the LORD."
