'House of Judah' in the Bible

Then the men of Judah came, and they anointed David there as king over the house of Judah, and they told David, "The men of Jabesh-Gilead buried Saul."

So then, let your hands be strong and {be valiant}, for your lord Saul [is] dead, and the house of Judah has anointed me as king over them."

Ish-Bosheth the son of Saul [was] forty years old when he became king over Israel and he reigned two years; however, the house of Judah {followed} David.

The number of days that David was king over Hebron, over the house of Judah, [was] seven years and six months.
