Genesis 27:40

And Yahweh said to her, “Two nations are in your womb; And two peoples will be separated from your body; And one people shall be stronger than the other; And the older shall serve the younger.”

But Esau said, “I have plenty, my brother; let what you have be your own.”

Then he placed garrisons in Edom. In all Edom he placed garrisons, and all the Edomites became servants to David. And Yahweh granted salvation to David wherever he went.

So Edom revolted against Judah to this day. Then Libnah revolted at the same time.

By faith Isaac blessed Jacob and Esau, even regarding things to come.

For you know that even afterwards, when he desired to inherit the blessing, he was rejected, for he found no place for repentance, though he sought for it with tears.
