Kore's son Shallum, who was the grandson of Ebiasaph and the great-grandson of Korah, and the descendants of Korah (who were relatives of his ancestral house) were over the service responsibilities and served as guardians of the entrances of the Tent, just as their ancestors had been in charge of the camp of the LORD and guardians of the entrance.

and David went out to meet them. He told them, "If you've come in peace to be of help to me, then you'll have my commitment. But if you've come to betray me to my enemies, even though I'm innocent of wrongdoing, then may the God of our ancestors watch and judge."

LORD God of Abraham, Isaac, and Israel, our ancestors, keep your purposes and thoughts constantly in the hearts of your people and direct their hearts toward you,

Then David told the entire assembly, "Bless the LORD your God, please." So the entire assembly blessed the LORD God of their ancestors, bowing their heads and falling in the LORD's presence and before the king.
