Judges 8:27-31

Gideon made it into an ephod, and placed it in his city, Ophrah; but all Israel committed infidelity with it there, and it became a snare to Gideon and his household. Forty Years of Peace

So Midian was subdued before the sons of Israel, and they did not lift up their heads anymore. And the land was undisturbed for forty years in the days of Gideon.

Then Jerubbaal the son of Joash went and lived in his own house.

Now Gideon had seventy sons who were his direct descendants, for he had many wives.

And his concubine who was in Shechem also bore him a son, and he named him Abimelech.
