The same power which God had and put forth for his people in ancient time, he still hath in as great vigour as ever, and is not at all weakened by age, and is as able and ready to act for them now as ever he was; which he hath showed by this late and glorious instance. His eyes behold the nations; he sees all their secret and subtle devices, and can and will defeat them, when he sees fit. Let not the rebellious exalt themselves; lift up their hands against God, or against his people. Or, the rebellious (i.e. those people which rebel against this almighty God and his laws) shall not exalt themselves, as they vainly hope and design to do; but shall be brought down and destroyed, as is hereby implied.
