After experiencing double darkness for eight years with Cushan Rishathaim, and eighteen years under the heavy weight of Eglon King of Moab, Israel for twenty years have been oppressed by Jabin King of Hazor a northern Canaanite city stronghold, and his general Sisera. After each time that God delivers Israel from the grip of the enemy and they willfully go back into disobedience-idolatry the length of time of their bondage increases, proving you may pick the sin, but you cannot choose the punishment or the amount of time served.
