On the same basis, you would not be able to point to anyone of the past generations approaching a pregnant woman in the pages of Scripture. Only later, after the birth and weaning of the child, would you again find the wives in physical relations with their husbands. You will find that Moses’ father observed this point. He left a three-year gap after Aaron’s birth before fathering Moses.
[AD 215] Clement of Alexandria on Exodus 7:7
