She got it from the bible and must have liked the sound of it.
I don't remember that name from those Bible study days at Sunday School
Tiglath-Pileser III ( 𒆪𒋾𒀀𒂍𒈗𒊏 - see if that comes out), and he's one of those who tried to do the Israelites a bit of no good.
He's mentioned in Kings and Chronicles, and having looked it up I might as well quote wiki:
Biblical records describe how Tiglath-Pileser III exacted 1,000 talents of silver as tribute from King Menahem of the Kingdom of Israel (2 Kings 15:19) and later defeated his successor Pekah (2 Kings 15:29).
Pekah had allied with Rezin, king of the Arameans against Ahaz (known to the Assyrians as Yahu-khazi), of the Kingdom of Judah, who responded by appealing for the Assyrian monarch's help with the Temple gold and silver. Tiglath-Pileser answered swiftly. He first marched his army down the eastern Mediterranean coast, taking coastal cities all the way to Egypt. This cut off his enemies' access to the sea. Once this was achieved, he returned to the Northern Kingdom of Israel, destroyed their army, and deported the Reubenites, Gadites, and the people of Manasseh to Halah, Habor, Hara, and the Gozan river (1 Chron 5:26). He then installed an Israelite puppet king, Hoshea, (732–723 BCE) in the place of Pekah. He concluded this extensive campaign by marching north and west, ravaging Aramaea, seizing Damascus, executing Rezin, and deporting the survivors to Kir (2 Kings 16:9).
Beyond this, the Assyrian alliance was not beneficial to Ahaz (2 Chron 28:20).
I'm glad to have found all that though, so thanks.
