The Assyrian captivity (or Assyrian exile) is the period in the history of Ancient Israel and Judah during which several thousand Israelites of ancient Samaria were resettled as captives by Assyria. The Northern Kingdom of Israel was conquered by the Neo-Assyrian monarchs, Tiglath-Pileser III (Pul) and Shalmaneser V. The later Assyrian rulers Sargon II and his son and successor, Sennacherib, were responsible for finishing the twenty-year demise of Israel’s northern ten-tribe kingdom, although they did not overtake the Southern Kingdom. Jerusalem was besieged, but not taken. The tribes exiled by Assyria later became known as the Ten Lost Tribes.
The captivities began in approximately 740 BC (or 733/2 BC according to other sources).
And the God of Israel stirred up the spirit of Pul king of Assyria, and the spirit of Tilgathpilneser king of Assyria, and he carried them away, even the Reubenites, and the Gadites, and the half tribe of Manasseh, and brought them unto Halah, and Habor, and Hara, and to the river Gozan, unto this day. (I Chronicles 5:26)
In the days of Pekah king of Israel came Tiglathpileser king of Assyria, and took Ijon, and Abelbethmaachah, and Janoah, and Kedesh, and Hazor, and Gilead, and Galilee, all the land of Naphtali, and carried them captive to Assyria. (II Kings)
In 722 BC, nearly twenty years after the initial deportations, the ruling city of the Northern Kingdom of Israel, Samaria, was finally taken by Sargon II after a three-year siege started by Shalmaneser V.
Against him came up Shalmaneser king of Assyria; and Hoshea became his servant, and gave him presents.
And the king of Assyria found conspiracy in Hoshea: for he had sent messengers to So king of Egypt, and brought no present to the king of Assyria, as he had done year by year: therefore the king of Assyria shut him up, and bound him in prison. Then the king of Assyria came up throughout all the land, and went up to Samaria, and besieged it three years.
In the ninth year of Hoshea the king of Assyria took Samaria, and carried Israel away into Assyria, and placed them in Halah and in Habor by the river of Gozan, and in the cities of the Medes. (II Kings 17:3–6)
And the king of Assyria did carry away Israel unto Assyria and put them in Halah and in Habor by the river of Gozan, and in the cities of the Medes: because they obeyed not the voice of the LORD their God, but transgressed his covenant, and all that Moses the servant of the LORD commanded and would not hear them, nor do them.
