viper 
c.1520, from M.Fr. vipere, from L. vipera "viper, snake, serpent," from vivus "alive, living" (see vital) + parere "bring forth, bear" (see pare). It formerly was believed (mistakenly) that the viper does not lay eggs. Applied to persons of spiteful character since at least 1591. The only venomous snake found in Great Britain. Replaced native adder. "The flesh of the viper was formerly regarded as possessing great nutritive or restorative properties, and was frequently used medicinally" [OED]; hence viper wine, wine medicated with some kind of extract from vipers, used 17c. by "gray-bearded gallants" in a bid "to feele new lust, and youthfull flames agin."

Viper

In Job 20:16, Isa. 30:6; 59:5, the Heb. word eph'eh is thus rendered. The Hebrew word, however, probably denotes a species of poisonous serpents known by the Arabic name of 'el ephah. Tristram has identified it with the sand viper, a species of small size common in sandy regions, and frequently found under stones by the shores of the Dead Sea. It is rapid in its movements, and highly poisonous. In the New Testament _echidne_ is used (Matt. 3:7; 12:34; 23:33) for any poisonous snake. The viper mentioned in Acts 28:3 was probably the vipera aspis, or the Mediterranean viper. (See ADDER.)
