Hosea ben Beeri first started talking to God back when when Jeroboam was king of Israel.
The first thing God told Hosea was to go find a slutty woman and marry her to represent how God currently felt about Israel. So Hosea searched and searched and eventually found Gomer, the most promiscuous girl in town.
He decided to assume the kids were his. The first one was a boy and God told him to name it Jezreel, in honor of the massacre of Israelites in Jezreel that God had planned. The next one was a girl. God said to name it Not Loved, because that’s how It felt about Israel. The third kid was named Not My People, because God was breaking up with Israel.
