Genesis 27:37

27:37 Isaac replied to Esau, “Look! I have made him lord over you. I have made all his relatives his servants and provided him with grain and new wine. What is left that I can do for you, my son?”

Genesis 27:40

27:40 You will live by your sword

but you will serve your brother.

When you grow restless,

you will tear off his yoke

from your neck.” ¹ 

[27:40]  ¹ sn You will tear off his yoke from your neck. It may be that this prophetic blessing found its fulfillment when Jerusalem fell and Edom got its revenge. The oracle makes Edom subservient to Israel and suggests the Edomites would live away from the best land and be forced to sustain themselves by violent measures.
