'House of Judah' in the Bible

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

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

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