Judges 6:1The Israelites did evil in the eyes of the Lord, and for seven years he gave them into the hands of the Midianites. 2 Because the power of Midian was so oppressive, the Israelites prepared shelters for themselves in mountain clefts, caves and strongholds. 3 Whenever the Israelites planted their crops, the Midianites, Amalekites and other eastern peoples invaded the country. 4 They camped on the land and ruined the crops all the way to Gaza and did not spare a living thing for Israel, neither sheep nor cattle nor donkeys. 5 They came up with their livestock and their tents like swarms of locusts. It was impossible to count them or their camels; they invaded the land to ravage it. 6 Midian so impoverished the Israelites that they cried out to the Lord for help.

7 When the Israelites cried out to the Lord because of Midian, 8 he sent them a prophet, who said, “This is what the Lord, the God of Israel, says: I brought you up out of Egypt, out of the land of slavery. 9 I rescued you from the hand of the Egyptians. And I delivered you from the hand of all your oppressors; I drove them out before you and gave you their land. 10 I said to you, ‘I am the Lord your God; do not worship the gods of the Amorites, in whose land you live.’ But you have not listened to me."

This is from the easy English site.

The Israelites soon forgot about Deborah’s success and they behaved in their old ways again. The new enemies were people from Midian and Amalek’s people. They were ‘too many’ in number, so that Israel’s people could not defeat them. Their plan was what we today call a ‘scorched (burnt) earth plan’. This means that they destroyed everything on the land so that Israel’s people could not grow food there. God told the people what he had done for them. Then he told them what they had done to him. God had heard their voice, but they had not listened to him. He had done very many kind things for them, but they still did wrong things. So God had to notice those wrong things and he had to punish Israel’s people. And this was the result. He sent to them too many people from Midian.

These are actually some distant cousins of the children of Israel. These are the descendants of Abraham's concubines. It's in Genesis 25:1-6.. I guess I could have titled this "the relatives from hell come to visit".
