Judges 7:12 Meaning and Commentary

Judges 7:12

And the Midianites and the Amalekites, and the children of the
east
The Arabians, who with the Amalekites joined the Midianites in this expedition:

lay along in the valley
in the valley of Jezreel, in their tents, which overspread the valley, or at least great part of it:

like grasshoppers for multitude;
or locusts, which usually come in great numbers, and cover the air and the sun where they fly, and the earth where they light, as they did the land of Egypt; this army consisted at least of 135,000 men, as is clear from ( Judges 8:10 )

and their camels were without number; as the sand is by the sea side
for multitude;
an hyperbolical expression, setting forth the great number of them which the countries of Midian and Arabia abounded with; and were very proper to bring with them, to load and carry off the booty they came for, the fruits of the earth; see ( Judges 6:4 Judges 6:5 ) .

13 And Gedeon came, and behold a man relating to his neighbour a dream, and he said, Behold, I have dreamed a dream, and behold, a cake of barley bread rolling into the camp of Madiam, and it came as far as a tent, and smote it, and it fell, and it turned it up, and the tent fell.
14 And his neighbour answered and said, This is none other than the sword of Gedeon, son of Joas, a man of Israel: God has delivered Madiam and all the host into his hand.
