The Bible paints the Philistines as the main enemy of the Israelites (prior to the rise of the Neo-Assyrian Empire between the 10th century BC and late 7th century BC) with a state of almost perpetual war between the two. The Philistine cities lost their independence to Assyria, and revolts in the following years were all crushed. They were subsequently absorbed into the Neo-Babylonian Empire and the Achaemenid Empire, and disappeared as a distinct ethnic group by the late 5th century BC.[45]
