Job 41:1

Leviathan. A transliteration of the Hebrew liwyathan. Liwyathan is also translated “their mourning” (see on chapter 3:8; see also Psalm 74:14; 104:26; Isaiah 27:1). The creature is represented as wild, fierce, and ungovernable, having a mouth of large size and armed with a formidable array of teeth. The body is covered with scales set near together, like a coat of mail. Whether Job is here describing the crocodile, as many commentators think, or some monster now extinct, cannot be established.

With a cord. Wild animals were often led along by a rope attached to their mouths, as Assyrian sculptures reveal. God asks whether the great leviathan can be caught with a fishhook or led along by tying a rope around its jaw. This question, like others that have preceded, accentuates the weakness of man compared with the creative power of God.
