2 Kings 17:5-17
II Kings 17:7-17 catalogs the sins of Israel:
» Widespread idolatry. Israel "feared other gods" (verse 7). "They built for themselves high places in all their cities . . . . They set up for themselves sacred pillars and wooden images on every high hill and under every green tree; and there they burned incense on all the high places, as the nations had done whom the LORD had carried away before them." (verses 9-11). Further, they "followed idols, became idolaters, and . . . made for themselves a molded image and two calves, made a wooden image and worshipped all the host of heaven, and served Baal" (verses 15-16).
» Pagan Religious Practices. The Israelites "caused their sons and daughters to pass through the fire, practiced witchcraft and soothsaying, and sold themselves to do evil in the sight of the LORD, to provoke Him to anger" (verse 17).
» Rejection of God's Law. Israel "walked in the statutes of the nations whom the LORD had cast out from before the children of Israel." (verse 8). Verse 15 points out that the people "rejected [God's] statutes and His covenant that He had made with their fathers, and His testimonies which He had testified against them." The prophet Amos particularizes the epidemic of social injustice in the Kingdom of Israel. As an example, notice Amos 2:6-7, where Amos chides the Israelites: ". . . because they sell the righteous for silver, and the poor for a pair of sandals. They pant after the dust of the earth which is on the head of the poor, and pervert the way of the humble." The Israelites displayed a pandemic failure to love their fellow man.
II Kings 17:5-6 relates the ultimate consequence.
Now the king of Assyria went throughout all the land, and went up to Samaria and besieged it for three years. . . . The king of Assyria took Samaria and carried Israel away to Assyria, and placed them in Halah and by the Habor, the River of Gozan, and in the cities of the Medes.
Assyria, a kingdom known as much for its innovative weapons as for their brutal implementation, conquered the Kingdom of Israel in 718 BC. So it was that, about 250 years after it was established, the ten-tribed northern kingdom became extinct as a sovereign nation. The Assyrians deported the population en masse from its homeland in Canaan, transplanting it virtually in toto to the southern shores of the Caspian Sea. The Kingdom of Israel fell below the historian's radar.

Searching for Israel (Part Six): Israel Is Fallen, Is Fallen

The king of Assyria invaded the land, besieging Samaria for three years as detailed in 2 Kings 17:5. This military action came as a consequence of Israel's widespread sins, including idolatry, pagan practices, and rejection of God's laws. The Israelites worshipped other gods, built high places, and engaged in witchcraft, provoking divine anger. They also practiced social injustice, selling the righteous and oppressing the poor. Following the siege, the king of Assyria captured Samaria, deporting the population to regions like Halah, Habor, and the cities of the Medes, effectively ending the northern kingdom's sovereignty and removing them entirely from Canaan, transplanting them to distant lands.
