2 Kings 15:30

And Hoshea the son of Elah made a conspiracy against Pekah the son of Remaliah, and smote him, and slew him, and reigned in his stead, in the twentieth year of Jotham the son of Uzziah.

Hoshea the son of Elah formed a conspiracy against Pekah the son of Remaliah, struck him and killed him, and reigned in his stead. This change of kings belonged to a continued history of war, strife, conspiracy and short troubled reigns in the ten-tribe kingdom, namely Menahem, Pekahiah, Pekah and Hoshea, following the end of Jehu's dynasty with Zachariah and Shallum, when Israel was increasingly subject to foreign powers. Hoshea who followed Pekah was the last king of Israel, and his reign was the reign in which the kingdom came to an end. Tiglath-pileser placed Hoshea on the throne of Samaria in 730 B.C.

An Assyrian inscription likewise names Pekah as the king who had been slain and Hoshea as the man appointed to rule Samaria, adding that Assyria received tribute from them and sent people and goods from the land to Assyria. The conspiracy, killing and succession fulfill the prediction in Isaiah 8:1-4 that Assyria would bring ruin upon Samaria, occurring within the short period signified by the meaning of the child's name concerning speedy spoil and hastening prey. The kingdom was overthrown under Hoshea and many of its people taken captive, by invasion of Shalmaneser of Assyria, with the conquest completed by his successor Sargon, after which the tribes were carried away into captivity and scattered. Israel's history ending in captivity after the Assyrians came was a consequence of the kingdom's departure from God through idolatry.
