His skin is wasted by disease, and his body is food for the worst of diseases.

Let it devour the beauty of his skin; let the ancient death consume his arms.

It shall devour the strength of his skin - Margin, bars. The margin is a correct translation of the Hebrew. The word used (בדי badēy, construct with עורו ‛ôrô - his skin) means bars, staves, branches, and here denotes his limbs, members; or, more literally, the bones, as supports of the skin, or the human frame. The bones are regarded as the bars, or the framework, holding the other parts of the body in their place, and over which the skin is stretched. The word "it" here refers to the "first-born of death" in the other hemistich of the verse; and the meaning is, that the strength of his body shal be entirely exhausted.
The first-born of death - The "first-born" is usually spoken of as distinguished for vigor and strength; Genesis 49:3, "Reuben, thou art my first-born, my might, and the beginning of my strength;" and the idea conveyed here by the "first-born of death" is the most fearful and destructive disease that death has ever engendered; compare Milton's description of the progeny of sin, in Paradise Los. Diseases are called "the sons or children of death" by the Arabs, (see Schultens in loc.,) as being begotten by it.

It shall devour the strength of his skin - This may refer to the elephant, or to the rhinoceros, whose skin scarcely any dart can pierce: but in the case referred to above, the animal is taken in a pitfall, and then the first-born of death - a sudden and overwhelming stroke - deprives him of life. See the account of hunting the elephant in the East at the end of the chapter, Job 18:21 (note). The Chaldee has: "The strength of his skin shall devour his flesh; and the angel of death shall consume his children."

It shall devour the strength of his skin: [even] the (h) firstborn of death shall devour his strength.
(h) That is, some strong and violent death will consume his strength: or as the Hebrew word signifies his members or parts.

It shall devour the strength of his skin,.... Or "the bars of his skin" (x), the strength and support of his body, for which his skin may be put, as the bones; or "the branches of his skin" (y), the veins, which like so many branches run under, and may be seen through the skin: now these, it, famine, or want of food, devours, and destroys the strength and beauty of the skin, cause it to be black like an oven, Lamentations 4:8; bring a man to a mere skeleton, to skin and bones, waste and consume the members of his body, his flesh, and blood, and bones; the Targum, Jarchi, and Aben Ezra, by "his bars" or "branches" understand his children, which are his bars, the strength of him, and are to him as branches to a tree, proceeding from him; and if we render it, as some do, he "shall devour" (z), or "eat", that is, the wicked man, it points to us the most horrible scene in a famine, which is shocking and shuddering, and yet what has been, as in the sieges of Samaria and Jerusalem, a parent's eating and devouring his own children, 2-Kings 6:28; but rather the "it is the firstborn of death", in the next clause, which is to be supplied from thence here:
even the firstborn of death shall devour his strength; and so Mr. Broughton translates the whole verse,
"a strange death shall eat all the branches of his body, all its branches shall it eat;''
which the Targum interprets of the angel of death, him which has the power of death: but rather it signifies not what presides over death, but what death first produces, which are corruption and rottenness, dust and worms; these are the firstborn of death, or the firstfruits and effects of it, and which devour and destroy not the skin only, but the whole body and all its members: or "the firstborn death" (a); death, which is a firstborn, it is the firstborn of sin; sin is its parent, last conceives sin, and that brings forth death; death is the child of sin, and is its firstborn, and sin entered into the world, and death by sin; and this is what devours and destroys the strength of men. Some understand by firstborn death a premature one, death before the usual time or common course of nature; wicked men do not live out half their days; and when they are taken off in their youth, in the prime of their days and strength, and amidst all their wealth, riches, and pleasures, this is the first, or firstborn death, as that is a secondary one which is late, in the time of old age. This is the ingenious thought of Pineda; but, perhaps, rather, as the firstborn is the chief and principal, so here may be meant the chiefest of deaths, the most hard, cruel, and severe; the first of those, that death has under it, which are principally the sword, famine, pestilence, and the noisome beast, see Revelation 6:8; it is commonly thought that famine is intended, spoken of in the context; but why not rather some thing distinct from it, and particularly the pestilence? since that is emphatically called death by the Jews, and in the passage last referred to, and is the terror by night, and the arrow that flies by day, even the pestilence that walks in darkness, and the destruction that wastes at noonday; by means of which thousands and ten thousands of wicked men fall at the sides of good men, when it does not affect them: and so may be the evil particularly threatened to a wicked man here, see Psalm 91:5.

UMBREIT has "he" for "it," that is, "in the rage of hunger he shall devour his own body"; or, "his own children" (Lamentations 4:10). Rather, "destruction" from Job 18:12 is nominative to "devour."
strength--rather, "members" (literally, the "branches" of a tree).
the first-born of death--a personification full of poetical horror. The first-born son held the chief place (Genesis 49:3); so here the chiefest (most deadly) disease that death has ever engendered (Isaiah 14:30; "first-born of the poor"--the poorest). The Arabs call fever, "daughter of death."

First - born - A terrible kind of death. The first - born was the chief of his brethren, and therefore this title is given to things eminent in their kind.
