One dieth in his full strength - Margin, "very perfection," or, "in the strength of his perfection." The meaning is, that he dies in the very prime and vigor of life, surrounded with everything that can contribute to comfort. Of the truth of this position, no one can doubt; and the wonder is, that the friends of Job had not seen or admitted it.
Being wholly at ease and quiet - That is, having everything to make them happy, so far as external circumstances are concerned. He is borne down by no calamities; he is overwhelmed by no sudden and heavy judgments. The phrase in this verse rendered "full strength" (תמו בעצם be‛etsem tômô), is literally, "in the bone of his perfection." It means full prosperity.

One dieth in his full strength - In this and the three following verses Job shows that the inequality of fortune, goods, health, strength, etc., decides nothing either for or against persons in reference to the approbation or disapprobation of God, as these various lots are no indications of their wickedness or innocence. One has a sudden, another a lingering death; but by none of these can their eternal states be determined.

One (m) dieth in his full strength, being wholly at ease and quiet.

One dieth in his full strength,.... Man is born a weak feeble creature, and it is by degrees, and through various stages of infancy, childhood, and youth, that he arrives to his full strength in manhood; and, when he does, sometimes so it is, that his strength is not weakened in the course of his life by a train of disorders and diseases, as it is in some; but death seizes and carries him off in the prime of his days, and in the fulness of his strength; for no strength of man, even the greatest, is a security against death: thousands die before they come to their full strength, and multitudes after it begins to decay; and when it is almost wasted, through the force of distempers, or the infirmities of old age, and others, as here, when their strength is in its highest rigour and utmost perfection, and all as God pleases: the words may be rendered "in the strength of his integrity", or "of his perfection" (f); in the Targum and Ben Gersom, and so Mr. Broughton, "in his very perfection"; and the word is sometimes used, in a moral and spiritual sense, of the integrity of a man's heart, and the uprightness of his ways and walk, and of the perfection of his state God-ward; see Job 1:1; and such a man who is upright in heart and conversation, who is truly gracious, sincerely a good man, and perfect through the complete righteousness of Christ, he dies such, his integrity continues with him to the last; and his graces being brought to maturity, he comes to his grave like a shock of corn in its season, and is found in the perfect righteousness of his living Redeemer: but it seems best to take the words in a natural and literal sense, as before; or to interpret them of the fulness of outward felicity, which some men arrive unto, and die in the midst of, when they have got to the highest degree of honour and grandeur, and attained to the greatest degree of wealth and riches, it could well be supposed they would; and then, when in the perfection of it, have been taken away by death; both these senses may stand together: it follows,
being wholly at ease and quiet; in easy circumstances, having an affluence of all good things, and nothing to disturb them, nor are in trouble as others, or plagued as they be; having all that heart can wish, or more, and without any pains of body, at least any long and continued ones; while others are attended with them, days, and months, and years, before their death, Job 33:19; whereas these go down to the grave in a moment, feeling little or no pain, and are quiet and easy in their minds, thoughtless of a future state, and unconcerned how it will be with them in another world; having no sight nor sense of sin, of the evil nature and just demerit of it, feel not the weight and burden of it in their consciences; have no concern or grief of mind for sins of omission or commission, no godly sorrow for it, or repentance of it, nor any fears of wrath and ruin, hell and damnation; but as they are at ease from their youth, with respect to those things, so they live and so they die, secure, stupid, and senseless. Some interpret this of good men (g); and it is not to be wondered at that a man that dies in his integrity, in the perfection of grace, holiness, and righteousness, should be at ease and quiet; who has an interest in the God of peace, whose peace is made by the blood of Christ, his Peacemaker, and who has a conscience peace arising from a comfortable view of the peace speaking blood, righteousness, and sacrifice of the Mediator; who knows his state is safe, being interested in everlasting love, in an unchangeable covenant in God, as his covenant God, in Jesus his living Redeemer; and knows where he is going, to heaven, to happiness and glory, to be with God, with Christ, with holy angels and glorified saints: but the former sense seems best, of a man dying in easy circumstances, without pain of booty, or distress of mind, whether we understand it of a good man or bad man, though the latter is rather meant.
