Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour: Be sober - Avoid drunkenness of your senses, and drunkenness in your souls; be not overcharged with the concerns of the world.
Be vigilant - Awake, and keep awake; be always watchful; never be off your guard; your enemies are alert, they are never off theirs.
Your adversary the devil - This is the reason why ye should be sober and vigilant; ye have an ever active, implacable, subtle enemy to contend with. He walketh about - he has access to you everywhere; he knows your feelings and your propensities, and informs himself of all your circumstances; only God can know more and do more than he, therefore your care must be cast upon God.
As a roaring lion - Satan tempts under three forms:
1. The subtle serpent; to beguile our senses, pervert our judgment, and enchant our imagination.
2. As an angel of light; to deceive us with false views of spiritual things, refinements in religion, and presumption on the providence and grace of God.
3. As a roaring lion; to bear us down, and destroy us by violent opposition, persecution, and death. Thus he was acting towards the followers of God at Pontus, etc., who were now suffering a grievous persecution.
Walketh about - Traversing the earth; a plain reference to Job 2:2, which see.
Seeking whom he may devour - Τινα καταπιῃ· Whom he may gulp down. It is not every one that he can swallow down: those who are sober and vigilant are proof against him, these he May Not swallow down; those who are drunken with the cares of this world, etc., and are unwatchful, these he May swallow down. There is a beauty in this verse, and a striking apposition between the first and last words, which I think have not been noticed: Be sober, νηψατε from νη, not, and πιειν to drink; do not drink, do not swallow down: and the word καταπιῃ, from κατα, down, and πιειν, to drink. If you swallow strong drink down, the devil will swallow you down. Hear this, ye drunkards, topers, tipplers, or by whatsoever name you are known in society, or among your fellow sinners. Strong drink is not only the way to the devil, but the devil's way into you; and Ye are such as the devil particularly May swallow down.
