This Shamgar was the third of the Judges which judged Israel. We have but a short account of him. But even this is as a Deliverer. As he rescued Israel from the Philistines, I am inclined to think the seat of his government lay south, and not to the east, on the banks of Jordan, as the situation of Ehud`s must have been. It is probable that Shamgar's deliverance of Israel was suddenly effected, as the weapon by which he wrought it should seem to intimate. What instruments are too weak when the Lord commissions them! Rams horns can blow down the walls of Jericho, and the foolishness of preaching turn men from darkness to light, when the Lord gives the word. Joshua 6:20; 1 Corinthians 1:21.
