Charles Ellicott Commentary Hosea 12:14

"Ephraim hath provoked to anger most bitterly: therefore shall his blood be left upon him, and his reproach shall his Lord return unto him." — Hosea 12:14 (ASV)

But the rift in the clouds closes again, and another severe rebuke follows. “Jacob” and “Israel” yield to the proud tribal name of Ephraim. This portion of the whole house of Israel incurs the charge. Read: Ephraim has provoked bitter feeling. The bloodguiltiness of Moloch sacrifices and other iniquity God will not remove. (Genesis 27:28–29, which form the basis for these references.)
