'House of Judah' in the Bible

But I will have mercy upon the house of Judah, and will save them by Jehovah their God; and I will not save them by bow, or by sword, or by battle, or by horses, or by horsemen.

And I will be unto Ephraim as a moth, and to the house of Judah as rottenness.

For I will be unto Ephraim as a lion, and as a young lion to the house of Judah. I, I will tear and go away; I will carry off, and there shall be none to deliver.
