Bereshit 26:32

³² ויהי ביום ההוא ויבאו עבדי יצחק ויגדו לו על־אדות הבאר אשר חפרו ויאמרו לו מצאנו מים׃

Isaac

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

¹⁹ God said, "No, but Sarah, your wife, will bear you a son. You shall call his name Isaac. I will establish my covenant with him for an everlasting covenant for his seed after him.
