Leviathan (jointed monster). This word occurs five times in the A. V., and once in the margin, Job 3:8, where the text has "mourning." In Hebrew the word livya-than is found only in Job 3:8; Job 41:1; Psalms 74:14; Psalms 104:26; Isaiah 27:1. In the margin of Job 3:8 and text of Job 41:1 the crocodile is no doubt the animal meant, and also in Psalms 74:14. In Psalms 104:26 the name represents some animal of the whale tribe in the Mediterranean; but it is uncertain what animal is intended in Isaiah 27:1. The term may denote some species of snakes which are common in south and west Africa.
