Arcana Coelestia#2214
2214. Verse 15 And Sarah denied it, saying, I did not laugh; for she was afraid. And He said, No, but you did laugh.
'And Sarah denied it, saying, I did not laugh; for she was afraid' means that human rational truth wished to make excuses for itself because it realized that it was not such as it ought to have been. 'And He said, No, but you did laugh' means that nevertheless it was such.
