'Household' in the Bible

Shallum son of Kore, son of Ebiasaph, son of Korah and his relatives from his ancestral household, the Korahites, were assigned to guard the thresholds of the tent. Their ancestors had been assigned to the Lord’s camp as guardians of the entrance.

Then all the people left for their homes, and David returned home to bless his household.

“Yet the Lord God of Israel chose me out of all my father’s household to be king over Israel forever. For He chose Judah as leader, and from the house of Judah, my father’s household, and from my father’s sons, He was pleased to make me king over all Israel.
