What is the meaning of the expression, "Because they knew that they were naked?" (Genesis 3:7).
They first arrived at the knowledge of this fact, that is to say, of their nakedness, after they had eaten of the forbidden fruit. Therefore, opinion was like the beginning of wickedness, when they perceived that they had not as yet used any covering, inasmuch as all parts of the universe are immortal and incorruptible; but they themselves immediately found themselves in need of some corruptible coverings made with hands. But this knowledge was in the nakedness itself, not as having been in itself the cause of any change, but because their mind now conceived a novelty unlike the rest of the universal world.
