🔼The name Shimeath in the Bible
There's only one Shimeath in the Bible. She was an Ammonitess and we know of her because her son Jozabad (according to 2 Kings 12:21) or Zabad (according to 2 Chronicles 24:26) killed king Joash of Judah.
He and his fellow regicide Jehozabad the son of the Moabitess Shomer (according to 2 Kings 12:21) or Shimrith (according to 2 Chronicles 24:26) were servants of Joash who struck him down at the house of Millo (according to 2 Kings) or when he was laying sick in his bed after a bout with a band of Arameans (according to 2 Chronicles).
Neither account makes clear why Joash had foreign servants, why they wanted to kill their king and what happened to them after.
