Judges 6:1

Midian] These desert nomads are regarded by the Hebrews as akin to them (Genesis 36:35 cp. Exodus 2:15). They are found in the neighbourhood of the peninsula of Sinai, and also wander northwards: on this occasion they pour westwards across the Jordan into the more fertile lands of Palestine. Like modern Bedouins they raid and harry and destroy, but make no permanent conquest. That the Israelites did not desert their homes is plain from Judges 6:11, etc.
