12 Ephraim a conspiracy of unrighteousness, his sin is hidden.

Osee 13:12 In-Context

10 Where is this thy king? let him even save thee in all thy cities: let him judge thee, of whom thou saidst, Give me a king and a prince.
11 And I gave thee a king in mine anger, and kept back in my wrath.
12 Ephraim a conspiracy of unrighteousness, his sin is hidden.
13 Pains as of a woman in travail shall come upon him: he is thy wise son, because he shall not stay in the destruction of children.
14 I will deliver out of the power of Hades, and will redeem them from death: where is thy penalty, O death? O Hades, where is thy sting? comfort is hidden from mine eyes.
