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

(c) The parts and members of the whale?

Jamieson-Fausset-Brown Bible Commentary

12. 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, De 19:4).

comely proportion-literally, "the comeliness of his structure" (his apparatus: so "suit of apparel" Jud 17:10) [Maurer]. Umbreit translates, "his armor." But that follows after.

Matthew Henry's Concise Commentary

41:1-34 Concerning Leviathan. - The description of the Leviathan, is yet further to convince Job of his own weakness, and of God's almighty power. Whether this Leviathan be a whale or a crocodile, is disputed. The Lord, having showed Job how unable he was to deal with the Leviathan, sets forth his own power in that mighty creature. If such language describes the terrible force of Leviathan, what words can express the power of God's wrath? Under a humbling sense of our own vileness, let us revere the Divine Majesty; take and fill our allotted place, cease from our own wisdom, and give all glory to our gracious God and Saviour. Remembering from whom every good gift cometh, and for what end it was given, let us walk humbly with the Lord.
