Genesis 27:39-40 AMPC
Then Isaac his father answered, Your [blessing and] dwelling shall all come from the fruitfulness of the earth and from the dew of the heavens above;
By your sword you shall live and serve your brother. But [the time shall come] when you will grow restive and break loose, and you shall tear his yoke from off your neck.
