EASTON’S BIBLE DICTIONARY (1897 EDITION)
Asp – (Heb. pethen), Deut. 32:33; Job 20:14, 16; Isa. 11:8.
It was probably the Egyptian cobra (Naja haje), which was very poisonous (Rom. 3:13; Gr. aspis).
The Egyptians worshipped it as the uraeus, and it was found in the desert and in the fields.
The peace and security of Messiah’s reign is represented by the figure of a child playing on the hole of the asp.
