All the sportive rollickings of all the animals, from the agile fawn to the unwieldly behemoth, are dances taught them by nature.
-- Ambrose Bierce, They All Dance
And while that's not the case here, the retail behemoth clearly has the captive attention of mainstream America.
-- Dave Herrera, "3OH!3 gets enviable Walmart co-sign, prepares to print its own money," Denver Westword, July, 2010.
Origin:
Behemoth derives from the Hebrew b'hemoth in the Book of Job, but may be a folk etymology of Egyptian pehemau , "water-ox," the name for the hippopotamus.
