And she conceived again, and bore a daughter. And [LORD] said to him, Call her name Lo-ruhamah, for I will no more have mercy upon the house of Israel, that I should in any way pardon them.

Hear this, O ye priests, and hearken, O house of Israel, and give ear, O house of the king, for to you pertains the judgment. For ye have been a snare at Mizpah, and a net spread upon Tabor.

I have seen a horrible thing in the house of Israel. Whoredom is there in Ephraim; Israel is defiled.

Ephraim encompasses me around with falsehood, and the house of Israel with deceit, but Judah yet rules with God, and is faithful with the Holy One.
