Numeri 32:20

²⁰ Quibus Moyses ait : Si facitis quod promittitis, expediti pergite coram Domino ad pugnam :

Isaac

'Isaac' signifies the Lord's interior self and His divine rational in reference to divine good.

¹³ Yahweh said to Abraham, "Why did Sarah laugh, saying, 'Will I really bear a child, yet I am old?'

¹⁴ Is anything too hard for Yahweh? At the set time I will return to you, when the season comes round, and Sarah will have a son."
