'House of Judah' in the Bible

But I will have mercy upon the house of Judah, and will save them by the LORD their God, and will not save them by bow, nor by sword, nor by battle, by horses, nor by horsemen.

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

For I will be to Ephraim as a lion, and as a young lion to the house of Judah: I, even I, will tear and go away; I will take away, and none shall rescue him.
