'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 unto Ephraim like a moth, and to the house of Judah like rottenness.

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