Thematic Bible: With the philistines oppressed israel for eighteen years

And again the children of Israel did evil in the eyes of the Lord, worshipping the Baals and Astartes, and the gods of Aram and the gods of Zidon and the gods of Moab and the gods of the children of Ammon and the gods of the Philistines; they gave up the Lord and were servants to him no longer. And the wrath of the Lord was burning against Israel, and he gave them up into the hands of the Philistines and into the hands of the children of Ammon. And that year the children of Israel were crushed under their yoke; for eighteen years all the children of Israel on the other side of Jordan, in the land of the Amorites which is in Gilead, were cruelly crushed down. read more.
