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 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.
