20:22 Trusting in their strength: The Lord suffered them to be overthrown and many of them to be slain, though their cause was just; partly in punishment of the idolatry which they exercised or tolerated in the tribe of Dan, and elsewhere; and partly because they trusted in their own strength; and therefore, though he bid them fight, he would not give them the victory, till they were thoroughly humbled and had learned to trust in him alone.
