'During' in the Bible

Brethren, do you not know--for I am writing to people acquainted with the Law--that it is during our lifetime that we are subject to the Law?

This accounts for the fact that if during her husband's life she lives with another man, she will be stigmatized as an adulteress; but that if her husband is dead she is no longer under the old prohibition, and even though she marries again, she is not an adulteress.
