Previous to the fall of Samaria, Tiglath-Pileser king of Assyria made several excursions into Israel. The biblical records mention three:
The first was against Menahem (2 Kings 15:19-20) but he was ‘bought off’ with money, and withdrew.
The second is mentioned in 1 Chron. 5:26, where he captured the 3 eastern tribes and deported them. “So the God of Israel stirred up the spirit of Pul king of Assyria, the spirit of Tiglath-pileser king of Assyria, and he took them into exile, namely, the Reubenites, the Gadites, and the half-tribe of Manasseh, and brought them to Halah, Habor, Hara, and the river Gozan, to this day.”
The third was against Pekah (2 Kings 15:29) when he captured several northern tribes. “In the days of Pekah king of Israel, Tiglath-pileser king of Assyria came and captured Ijon, Abel-beth-maacah, Janoah, Kedesh, Hazor, Gilead, and Galilee, all the land of Naphtali, and he carried the people captive to Assyria.”
My question relates to the last 2 cases. Did the invasion of the east of Israel, and the invasion of the north, happen at the same time? They would have both been during the reign of Pekah, but his reign lasted 20 years. So were they the same, or were they separate occasions? I would also be interested in Assyrian records that might add additional information to these biblical accounts.
