Judges 4:1-3

Then the sons of Israel again did evil in the sight of the Lord, after Ehud died.

So the Lord sold them into the hand of Jabin king of Canaan, who reigned in Hazor; and the commander of his army was Sisera, who lived in Harosheth-hagoyim.

The sons of Israel cried out to the Lord; for he had nine hundred iron chariots, and he oppressed the sons of Israel severely for twenty years.
