Hosea 1:4 - Wesley's Explanatory Notes

The blood — The slaughters made by Jehu's hand or by his order, in Jezreel. The house of Jehu — Which had now possessed the throne, through the reigns of Jehoahaz, Jehoash, and Jeroboam; but the usurper, and his successors adhering to the idolatry of Jeroboam the son of Nebat, and adding other sins to it, had now provoked God to declare a sudden extirpation of the family: all this came to pass when Shallum conspiring against Zechariah, slew him, 2 Kings 15:8-10. The kingdom — After one and forty years tottering it fell to utter ruin and hath so continued to this day.
