Hosea 5:3 KJV

I know Ephraim, and Israel is not hid from me: for now, O Ephraim, thou committest whoredom, and Israel is defiled.
Hosea 5:3, King James Version

In context

2 And the revolters are profound to make slaughter, though I have been a rebuker of them all.

3 I know Ephraim, and Israel is not hid from me: for now, O Ephraim, thou committest whoredom, and Israel is defiled.

4 They will not frame their doings to turn unto their God: for the spirit of whoredoms is in the midst of them, and they have not known the Lord.
