Here the apostle does three things: -

I.He shows them their danger from an enemy more cruel and restless than even the worst of men, whom he describes,

1.By his characters and names. (1.) He is an adversary: "That adversary of yours; not a common adversary, but an enemy that impleads you, and litigates against you in your grand depending cause, and aims at your very souls." (2.) The devil, the grand accuser of all the brethren; this title is derived from a word which signifies to strike through, or to stab. He would strike malignity into our natures and poison into our souls. If he could have struck these people with passion and murmuring in their sufferings, perhaps he might have drawn them to apostasy and ruin. (3.) He is a roaring lion, hungry, fierce, strong, and cruel, the fierce and greedy pursuer of souls.

2.By his business: He walks about, seeking whom he may devour; his whole design is to devour and destroy souls. To this end he is unwearied and restless in his malicious endeavours; for he always, night and day, goes about studying and contriving whom he may ensnare to their eternal ruin.

II.Hence he infers that it is their duty, 1. To be sober, and to govern both the outward and the inward man by the rules of temperance, modesty, and mortification. 2. To be vigilant; not secure or careless, but rather suspicious of constant danger from this spiritual enemy, and, under that apprehension, to be watchful and diligent to prevent his designs and save our souls. 3. To resist him stedfast in the faith. It was the faith of these people that Satan aimed at; if he could overturn their faith, and draw them into apostasy, then he knew he should gain his point, and ruin their souls; therefore, to destroy their faith, he raises bitter persecutions, and sets the grand potentates of the world against them. This strong trial and temptation they must resist, by being well-grounded, resolute, and stedfast in the faith: to encourage them to this,

III.He tells them that their care was not singular, for they knew that the like afflictions befell their brethren in all parts of the world, and that all the people of God were their fellow-soldiers in this warfare. Learn, 1. All the great persecutions that ever were in the world were raised, spirited up, and conducted, by the devil; he is the grand persecutor, as well as the deceiver and accuser, of the brethren; men are his willing spiteful instruments, but he is the chief adversary that wars against Christ and his people, Gen 3:15; Rev 12:12. 2. The design of Satan in raising persecutions against the faithful servants of God is to bring them to apostasy, by reason of their sufferings, and so to destroy their souls. 3. Sobriety and watchfulness are necessary virtues at all times, but especially in times of suffering and persecution. "You must moderate your affection to worldly things, or else Satan will soon overcome you." 4. "If you would overcome Satan, as a tempter, an accuser, or a persecutor, you must resist him stedfast in the faith; if your faith give way, you are gone; therefore, above all, take the shield of faith," Eph 6:16. 5. The consideration of what others suffer is proper to encourage us to bear our own share in any affliction: The same afflictions are accomplished in your brethren.

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.

Be sober, be vigilant,.... The apostle had exhorted to each of these before; see Pe1 1:13 but thought fit to repeat them; sobriety and watchfulness being exceeding necessary and useful in the Christian life; and the one cannot well be without the other: unless a man is sober in body and mind, he will not be watchful, either over himself or others, or against the snares of sin, Satan, and the world; and if he is not on his watch and guard, he is liable to every sin and temptation. The Syriac version renders the words, "watch", and "be ye mindful", or "remember"; watch with diligence, care, and industry, keeping a good lookout, minding and observing everything that presents, and remembering the power and cunning of the enemy; and the Ethiopic version renders them thus, "be ye prudent, and cause your heart to understand"; referring them not to temperance of body, but sobriety of mind, and to a prudent conduct and behaviour, as having a subtle as well as a malicious enemy to deal with:

because your adversary the devil; he who is a defamer and calumniator; who accuses God to men, and men to God, and is therefore styled the accuser of the brethren; he is the saints' avowed and implacable enemy. Satan is an enemy to mankind in general, but more especially to the seed of the woman, to Christ personal, and to Christ mystical, to all the elect of God: the word here used is a forensic term, and signifies a court adversary, or one that litigates a point in law, or opposes another in an action or suit at law. The Jews (c) have adopted this word into their language, and explain it by , "a law adversary", or one that has a suit of law depending against another. Satan accuses men of the breach of the law, and pleads that justice might take place, and punishment be inflicted, and which he pursues with great violence and diligence:

as a roaring lion; so called, both on account of his strength, and also because of his rage, malice, and cruelty, which he breathes out against the saints, who, though he cannot destroy them, will do all he can to terrify and affright them; so the young lions in Psa 104:21 are, by the Cabalistic Jews (d), understood of devils; to which, for the above reasons, they may be truly compared:

walketh about; to and fro in the earth; see Job 1:7 as a lion runs about here and there, when almost famished with hunger; and it also denotes the insidious methods, wiles, and stratagems Satan takes to surprise men, and get an advantage of them: he takes a tour, and comes round upon them, upon the back of them, at an unawares, so that they have need to be always sober, and upon their guard:

seeking whom he may devour; this is the end of his walking about: and the like is expressed in the Targum on Job 1:7

"and Satan answered before the Lord, and said, from going about in the earth , "to search into the works" of the children of men, and from walking in it;''

that so he might have something to accuse them of, and they fall a prey into his hands. This is the work he is continually employed in; he is always seeking to do mischief, either to the souls, or bodies, or estates of men, especially the former; though he can do nothing in either respect without a permission, not unless he "may"; and though this, with respect to body and estate, is sometimes granted, as in the case of Job, yet never with respect to the souls of any of God's elect, which are safe in Christ's hands, and out of his reach; this hinders not but that saints should be sober and watchful.

Peter has in mind Christ's warning to himself to watch against Satan, from forgetting which he fell.

Be sober . . . vigilant--"Care," that is, anxiety, will intoxicate the soul; therefore be sober, that is, self-restrained. Yet, lest this freedom from care should lead any to false security, he adds, "Be vigilant" against "your adversary." Let this be your "care." God provides, therefore do not be anxious. The devil seeks, therefore watch [BENGEL].

because--omitted in the oldest manuscripts The broken and disjointed sentences are more fervid and forcible. LUCIFER OF CAGLIARI reads as English Version.

adversary--literally, "opponent in a court of justice" (Zac 3:1). "Satan" means opponent. "Devil," accuser or slanderer (Rev 12:10). "The enemy" (Mat 13:39). "A murderer from the beginning" (Joh 8:44). He counteracts the Gospel and its agents. "The tempter."

roaring lion--implying his violent and insatiable thirst for prey as a hungry lion. Through man's sin he got God's justice on his side against us; but Christ, our Advocate, by fulfilling all the demands of justice for us, has made our redemption altogether consistent with justice.

walketh about-- (Job 1:7; Job 2:2). So the children of the wicked one cannot rest. Evil spirits are in Pe2 2:4; Jde 1:6, said to be already in chains of darkness and in hell. This probably means that this is their doom finally: a doom already begun in part; though for a time they are permitted to roam in the world (of which Satan is prince), especially in the dark air that surrounds the earth. Hence perhaps arises the miasma of the air at times, as physical and moral evil are closely connected.

devour--entangle in worldly "care" (Pe1 5:7) and other snares, so as finally to destroy. Compare Rev 12:15-16.
