They shouldn’t be divided.

The parents shouldn’t be divided in loving their children.

When Rebekah was pregnant,

The children struggled together within her (Gen. 25:21-22).

Then she said, “If it is so, why then am I this way?” 

“So she went to inquire of the Lord” (v. 22)

The Lord said to her, “Two nations are in your womb;

And two peoples will be separated from your body …” (v. 23).

But I think what God said “two people will be separated”

Can be applied to Rebekah and her husband Isaac

As their children Esau and Jacob born and were growing up:

“Now Isaac loved Esau, because he had a taste for game, but Rebekah loved Jacob” (v. 28).
