Hoshea was the last King of Israel , and he was evil, but after he was put in prison, the king of Assyria invaded the entire land, marched against Samaria and laid siege to it for three years. In the ninth year of Hoshea, the king of Assyria captured Samaria and deported the Israelites to Assyria. He settled them in Halah, in Gozan on the Habor River and in the towns of the Medes. All this took place because the Israelites had sinned against the LORD their God, who had brought them up out of Egypt from under the power of Pharaoh king of Egypt. They worshiped other gods 8 and followed the practices of the nations the LORD had driven out before them, as well as the practices that the kings of Israel had introduced. The Israelites secretly did things against the LORD their God that were not right. From watchtower to fortified city they built themselves high places in all their towns. They set up sacred stones and Asherah poles on every high hill and under every spreading tree. At every high place they burned incense, as the nations whom the LORD had driven out before them had done. They did wicked things that provoked the LORD to anger. They worshiped idols, though the LORD had said, "You shall not do this." [b] The LORD warned Israel and Judah through all his prophets and seers: "Turn from your evil ways. Observe my commands and decrees, in accordance with the entire Law that I commanded your fathers to obey and that I delivered to you through my servants the prophets." They forsook all the commands of the LORD their God and made for themselves two idols cast in the shape of calves, and an Asherah pole. They bowed down to all the starry hosts, and they worshiped Baal. They sacrificed their sons and daughters in [c] the fire. They practiced divination and sorcery and sold themselves to do evil in the eyes of the LORD, provoking him to anger. The Israelites persisted in all the sins of Jeroboam and did not turn away from them until the LORD removed them from his presence, as he had warned through all his servants the prophets. So the people of Israel were taken from their homeland into exile in Assyria, and they are still there. Look at the part that's green. It was true. Nahum, Jeremiah, Obadiah, Zephaniah, all those guys prophesied to Isreal and Judah. It wasn't just Elijah and Elisha.
The king of Assyria brought people from Babylon, Cuthah, Avva, Hamath and Sepharvaim and settled them in the towns of Samaria to replace the Israelites. They took over Samaria and lived in its towns. When they first lived there, they did not worship the LORD; so he sent lions among them and they killed some of the people. It was reported to the king of Assyria: "The people you deported and resettled in the towns of Samaria do not know what the god of that country requires. He has sent lions among them, which are killing them off, because the people do not know what he requires."Then the king of Assyria gave this order: "Have one of the priests you took captive from Samaria go back to live there and teach the people what the god of the land requires." So one of the priests who had been exiled from Samaria came to live in Bethel and taught them how to worship the LORD.
Nevertheless, each national group made its own gods in the several towns where they settled, and set them up in the shrines the people of Samaria had made at the high places. The men from Babylon made Succoth Benoth, the men from Cuthah made Nergal, and the men from Hamath made Ashima; the Avvites made Nibhaz and Tartak, and the Sepharvites burned their children in the fire as sacrifices to Adrammelech and to Anammelech, the gods of Sepharvaim.
So these guys are half and half guys, they counted God as one of the many gods they worshiped. Just so they didn't get eaten by lions.
