I will not conceal his parts, nor his power, nor his comely proportion.

I will not spare him, nor his mighty words, and framed to make supplication.

I will not be silent as to his parts, the story of his power, and the beauty of his structure.

I will not keep silence concerning his limbs, nor his mighty strength, nor his comely proportion.

I do not keep silent concerning his parts, And the matter of might, And the grace of his arrangement.

I will not keep quiet about the parts of his body, or about his power, and the strength of his frame.

Would I keep silence concerning his boastings, or his proud talk, or his fair array of words?

I will not spare him, nor his powerful words and counterfeit attempts at supplication.

I will not conceal his parts - This is the commencement of a more particular description of the animal than had been before given. In the previous part of the chapter, the remarks are general, speaking of it merely as one of great power, and not to be taken by any of the ordinary methods. A description follows of the various parts of the animal, all tending to confirm this general impression, and to fill the hearer with a deep conviction of his formidable character. The words rendered, "I will not conceal," mean, "I will not be silent;" that is, he would speak of them. The description which follows of the "parts" of the animal refers particularly to his mouth, his teeth, his scales, his eyelids, his nostrils, his neck, and his heart.
Nor his comely proportion - The crocodile is not an object of beauty, and the animal described here is not spoken of as one of beauty, but as one of great power and fierceness. The phrase used here (ערכוּ חין chı̂yn ‛êrekô) means properly "the grace of his armature," or the beauty of his armor. It does not refer to the beauty of the animal as such, but to the armor or defense which it had. Though there might be no beauty in an animal like the one here described, yet there might be a "grace" or fitness in its means of defense which could not fail to attract admiration. This is the idea in the passage. So Gesenius, Umbreit, and Noyes render it.

I will not conceal his parts - This is most certainly no just translation of the original. The Vulgate is to this effect: I will not spare him: nor yield to his powerful words, framed for the purpose of entreaty.
Mr. Good applies it to leviathan: -
"I cannot be confounded at his limbs and violence;
The strength and structure of his frame."
The Creator cannot be intimidated at the most formidable of his own works: man may and should tremble; God cannot.

I will not conceal (c) his parts, nor his power, nor his comely proportion.
(c) The parts and members of the whale?

I will not conceal his parts,.... The parts of the leviathan; or "his bars", the members of his body, which are like bars of iron:
nor his power; which is very great, whether of the crocodile or the whale:
nor his comely proportion; the symmetry of his body, and the members of it; which, though large, every part is in just proportion to each other.

I will not conceal--a resumption of the description broken off by the digression, which formed an agreeable change.
his power--literally, "the way," that is, true proportion or expression of his strength (so Hebrew, Deuteronomy 19:4).
comely proportion--literally, "the comeliness of his structure" (his apparatus: so "suit of apparel" Judges 17:10) [MAURER]. UMBREIT translates, "his armor." But that follows after.

12 I will not keep silence about his members,
The proportion of his power and the comeliness of his structure.
13 Who could raise the front of his coat of mail?
Into his double teeth-who cometh therein?
14 The doors of his face-who openeth them?
Round about his teeth is terror.
The Ker לו authorized by the Masora assumes an interrogative rendering: as to it, should I be silent about its members (לו at the head of the clause, as Leviticus 7:7-9; Isaiah 9:2), - what perhaps might appear more poetic to many. החרישׁ (once, Job 11:3, to cause to keep silence) here, as usually: to be silent. בּדּיו, as Job 18:13. דּבר signifies the relation of the matter, a matter of fact, as דּברי, facts, Psalm 65:4; Psalm 105:27; Psalm 145:5. חין (compared by Ew. with הין, a measure) signifies grace, χάρις (as synon. חסד), here delicate regularity, and is made easy of pronunciation from חנן, just as the more usual חן; the language has avoided the form חנן, as observed above. לבוּשׁ . clothing, we have translated "coat of mail," which the Arab. libâs usually signifies; פּני לבוּשׁו is not its face's covering (Schlottm.), which ought to be לבוּשׁ פּניו; but פּני is the upper or front side turned to the observer (comp. Isaiah 25:7), as Arab. wjh, (wag'h), si rem desuper spectes, summa ejus pars, si ex adverso, prima (Fleischer, Glossae, i. 57). That which is the "doubled of its mouth" (רסן, prop. a bit in the mouth, then the mouth itself) is its upper and lower jaws armed with powerful teeth. The "doors of the face" are the jaws; the jaws are divided back to the ears, the teeth are not covered by lips; the impression of the teeth is therefore the more terrible, which the substantival clause, Job 41:14 (comp. Job 39:20), affirms. שׁנּיו gen. subjecti: the circle, ἓρκος, which is formed by its teeth (Hahn).
