Now Sarah was listening at the entrance to the tent,
which was behind him.11
Abraham and Sarah were already very old,
and Sarah was past the age of childbearing.
12 So Sarah laughed to herself as she thought,
“After I am worn out
and my husband is old,
will I now have give birth ?”
13 Then the Lord said to Abraham,
“Why did Sarah laugh and say,
‘Will I really have a child,
now that I am old?
Rashi :
Her quote was changed
for the sake of peace
as she said also :" my husband is old,"
Aristotle
