'Descendants' in the Bible

But on Mount Zion there will be a remnant of those who escape, and it will be a holy place once again. The descendants of Jacob will conquer those who had conquered them.

The descendants of Jacob will be a fire, and the descendants of Joseph a flame. The descendants of Esau will be like stubble. They will burn them up and devour them. There will not be a single survivor of the descendants of Esau!" Indeed, the Lord has spoken it.
