It is based on this word “bakol.”
It means “with everything.”
A certain rabbi considered this word bakol and concluded this: for a man to have everything, he can’t only have a son. He must also have a daughter; her name was Bakol.
This is figurative, but the root of the teaching is lovely.
One of the attributes of God is “All.” This is “kol” in Hebrew. It is this principle that God is both the foundation and creator of “all things,” captured here in Isaiah:
This is what the Lord says, He who is your Redeemer, and the One who formed you from the womb:
“I, the Lord, am the Maker of all things,
Stretching out the heavens by Myself
And spreading out the earth alone,
Isaiah 44:24 (NASB)
But we also read that all the earth benefits from bakol. It is because of bakol.
Moreover the profit of the land is for all; even the king is served from the field.
Ecclesiastes 5:9 (NKJV)
The literal rendering of this verse in Ecclesiastes is “the profit of the land is bakol.”
If creation itself and all the land in it is blessed by kol, and then we go back to the beginning of creation and see that God made us male and female and in God’s image, bakol must hint at both a son and a daughter.
But these same rabbis say that this doesn’t need to be understood literally. It is a picture.
But also… the story brings in Rebekah, who will be like a daughter to Abraham in this chapter.
