'Eyes' in the Bible

It happened, when Joshua was by Jericho, that he lifted up his eyes and looked, and behold, a man stood in front of him with his sword drawn in his hand. Joshua went to him, and said to him, "Are you for us, or for our adversaries?"

know for a certainty that Yahweh your God will no longer drive these nations from out of your sight; but they shall be a snare and a trap to you, a scourge in your sides, and thorns in your eyes, until you perish from off this good land which Yahweh your God has given you.

When they cried out to Yahweh, he put darkness between you and the Egyptians, and brought the sea on them, and covered them; and your eyes saw what I did in Egypt: and you lived in the wilderness many days.
