Judges 6:1

Of Midian — For although the generality of the Midianites had been cut off by Moses about two hundred years ago, yet many of them doubtless fled into the neighbouring countries, whence afterwards they returned into their own land, and in that time might easily grow to be a very great number; especially, when God furthered their increase, that they might be a scourge for Israel when they transgressed. Let all that sin, expect to suffer: let all that turn to folly, expect to return to misery.
