'House of Judah' in the Bible

But I'll have mercy on the house of Judah, and I'll save them by the LORD their God I will not save them by the bow, by the sword, by battle, by horses, or by cavalry."

Therefore I will consume Ephraim like a moth, and the house of Judah as rottenness consumes.

Therefore I will be like a lion to Ephraim, and like a young lion to the house of Judah. I even I will tear them to pieces, and then I will leave. I will take them away, and there will be no rescue.
