And they were both naked, the man and his wife, and were not ashamed.
All Commentaries on Genesis 2:25 Go To Genesis 2
Ephrem The Syrian
AD 373
Following this it says, "The two of them were naked, but they were not ashamed. " [ Gen. 2:25 ] It was not because they were ignorant of what shame was that they were not ashamed; for had they been infants, as the pagans say, Scripture would not have said that "they were naked but were not ashamed," nor would it have spoken of "Adam and his wife" had they not been adults. The names which Adam gave should convince us of his wisdom, and the fact that it says that "he was to work it and guard it" is to indicate his strength. Likewise, the law laid down for them is meant to testify to their adulthood--and the transgression of the law to testify to their arrogance.
It was because of the glory in which they were wrapped that they were not ashamed. Once this had been taken away from them, after the transgression of the commandment, they were ashamed because they had been stripped of it, and the two of them rushed to the leaves in order to cover not so much their bodies as their shameful members.
