Victory and Defeat in the Promised Land

After 45 yrs of peace and prosperity Israel turned back into idolatry and it angered the Lord to the point where He left them to themselves and the Philistines, Ammonites, Amalekites, Amorites rose up and harassed, oppressed and distressed Israel for eighteen years. This is how long it took almost two decades before Israel cried out to The Lord, confessing that they have sinned against Him by serving the false gods of the nations around them, thus forsaking Jehovah God Who had delivered and blessed them continuously.
