"And the eyes of them both were opened, and they knew that they were naked; and they sewed fig leaves together, and made themselves aprons."
The phrase “the eyes of them both were opened” is “paw-kakh ah'-yin shet-tah'-yim” which means that their conscience was laid bare. Traditional thought has taught that it was their literal eyes were open. No. It was that their minds were opened to the concept of disobedience. The phrase “…and they know that they were naked” means that they were aware of and ashamed of their disobedience.
We should keep in mind that it wasn't the fruit that made them fall. It was the fact that they disobeyed a direct commandment from G-d. It could have easily been, "Don't pick the flowers".
Now come the interesting part. They made themselves a covering to hide their shame. There have been many sermons indicating that the fruit, which they ate, was an apple. Unfortunately, that comes from an erroneous Latin interpretation of the scriptures. If we back up and look at the whole counsel of G-d. There is one tree that is constantly withering, cursed or brought back to reconciliation, and that is the fig tree. This makes sense when you see that Adam and Eve attempted to hide their shame with the source of the disobedience.
I challenge you to perform a study of fig trees throughout the scriptures. I’m sure that it will be fruitful. ;-) Sorry for the pun, couldn’t resist the temptation. ;-) Better stop while I’m ahead.
