'Descendants' in the Bible

and say to them: "'This is what the sovereign Lord says: On the day I chose Israel I swore to the descendants of the house of Jacob and made myself known to them in the land of Egypt. I swore to them, "I am the Lord your God."

and the chamber which faces north is for the priests who keep charge of the altar. These are the descendants of Zadok, from the descendants of Levi, who may approach the Lord to minister to him."

"'But the Levitical priests, the descendants of Zadok who kept the charge of my sanctuary when the people of Israel went astray from me, will approach me to minister to me; they will stand before me to offer me the fat and the blood, declares the sovereign Lord.

This will be for the priests who are set apart from the descendants of Zadok who kept my charge and did not go astray when the people of Israel strayed off, like the Levites did.
