Verse 31. So let - That is, so suddenly, so surely, so effectual and irrecoverably. Deborah was a prophetess and this prayer was a prediction, that in due time all God's enemies shall perish. In his might - When he first riseth, and so goeth on in his course, which he doth with great might, even as a strong man that runneth a race, and so as no creature can stop, or hinder him; even so irresistible let thy people be. Such shall be the honour and such the joy of all that love God in sincerity, and they shall shine for ever as the sun in the kingdom of their father.
