Daughter is a Blessing (Chayei Sarah)

When Abraham was old, God blessed him with everything. That was a daughter. In Hebrew, "with everything" is spelled "Bakol," and that was the name of the daughter, Bakol.

The gematria of Bakol is 52. 

בכל = 2 + 20 + 30 = 52

This represents the name of God spelled with Hey

יהוה

יוד הה וו הה = 52

Thus, in a mystical sense, this name of God is the daughter of Abraham.
