The chapter begins with the word of the Lord to Hosea, son of Beeri, in the days of the kings of Judah Uzziah, Jotham, Ahaz and Hezekiah, and of Jeroboam son of Joash, king of Israel. God tells him to take a wife of whoredom and have children of whoredom, because the land has been committing great whoredom by forsaking the Lord. Hosea obeys and takes Gomer, the daughter of Diblaim. Interpreters differ on how to understand this command: some believe Gomer was already unfaithful or would be later, others see a symbolic action; in any case, Hosea's marriage is a picture of God's relationship with Israel.
Gomer conceives and bears a son. God tells Hosea to name him Jezreel, because in a little while he will punish the house of Jehu for the blood shed at Jezreel and put an end to the kingdom of the house of Israel; on that day he will break the bow of Israel in the Valley of Jezreel. Gomer then bears a daughter, whom God calls Lo-ruhamah, meaning not loved or shown no mercy, because he will no longer have mercy on Israel, though he will have mercy on Judah and save them not by bow or sword but by the Lord their God.
When Gomer has weaned Lo-ruhamah, she conceives and bears another son. God names him Lo-ammi, meaning not my people, because Israel is no longer his people and he is not their God. But the chapter does not end there. The number of the children of Israel will be like the sand of the sea, which cannot be measured or counted. In the place where it was said that they are not God's people, they will be called children of the living God. Judah and Israel will be gathered together, appoint one head and go up from the land, for great will be the day of Jezreel.
