Consider what happened to the first woman, Eve. Satan suggested that her eyes were “bound to be opened” if she would eat the fruit from “the tree of the knowledge of good and bad.” Eve must have been intrigued by the thought of having her eyes “opened.” Her interest in eating the forbidden fruit was further heightened when she “saw that the tree was good for food and that it was something to be longed for to the eyes, yes, the tree was desirable to look upon.” Looking at the tree with longing led Eve to disobey God’s command. Her husband, Adam, also disobeyed, with disastrous consequences to all humankind.—Gen. 2:17; 3:2-6; Rom. 5:12; Jas. 1:14, 15.
In the days of Noah, some angels were also influenced by what they saw. Referring to them, Genesis 6:2 relates: “The sons of the true God began to notice the daughters of men, that they were good-looking; and they went taking wives for themselves, namely, all whom they chose.” Lustfully looking upon the daughters of men aroused in the rebellious angels an unnatural desire for sexual relations with humans, and those angels fathered violent offspring. Man’s badness at that time resulted in the destruction of all mankind, with the exception of Noah and his family.—Gen. 6:4-7, 11, 12.
Centuries later, the Israelite Achan’s eyes seduced him into stealing some items from the captured city of Jericho. God had commanded that all things in that city should be destroyed except for certain things that were to be given to the treasury of Jehovah. The Israelites were warned: “Keep away from the thing devoted to destruction, for fear you may get a desire” and take some items from the city. When Achan disobeyed, the people of Israel suffered defeat at the city of Ai, and a number of them died. Achan did not admit to his theft until he was exposed. “When I got to see” the items, Achan said, “then I wanted them, and I took them.” The desire of his eyes led to his destruction, along with “everything that was his.” (Josh. 6:18, 19; 7:1-26) Achan desired in his heart what was forbidden to him.
