2 Kings 17:5-9

Then the king of Assyria invaded the entire land, and went up to Samaria and besieged it for three years. Israel Captive

In the ninth year of Hoshea, the king of Assyria captured Samaria and led the people of Israel into exile to Assyria, and settled them in Halah and Habor, on the river of Gozan, and in the cities of the Medes. Why Israel Fell

Now this came about because the sons of Israel had sinned against the Lord their God, who had brought them up from the land of Egypt, from under the hand of Pharaoh, king of Egypt; and they had feared other gods.

They also followed the customs of the nations whom the Lord had driven out from the sons of Israel, and in the customs of the kings of Israel which they had introduced.

And the sons of Israel did things secretly against the Lord their God which were not right. Moreover, they built for themselves high places in all their towns, from watchtower to fortified city.
