Did you know?

In the biblical book of Job, Behemoth is the name of a powerful grass-eating, river-dwelling beast with bones likened to bronze pipes and limbs likened to iron bars. Scholars have speculated that the biblical creature was inspired by the hippopotamus, but details about the creature’s exact nature are vague. The word first passed from the Hebrew word bĕhēmōth into Late Latin (the Latin used by writers in the third to sixth centuries), where, according to 15th century English poet and monk John Lydgate it referred to "a beast rude full of cursednesse." In modern English, behemoth functions as an evocative term for something of monstrous size, power, or appearance.
