Serpent

(Heb. nahash; Gr. ophis), frequently noticed in Scripture. More
than forty species are found in Syria and Arabia. The poisonous
character of the serpent is alluded to in Jacob's blessing on
Dan (Gen. 49:17; see Prov. 30:18, 19; James 3:7; Jer. 8:17).
(See ADDER T0000085.)

This word is used symbolically of a deadly, subtle, malicious
enemy (Luke 10:19).

The serpent is first mentioned in connection with the history
of the temptation and fall of our first parents (Gen. 3). It has
been well remarked regarding this temptation: "A real serpent
was the agent of the temptation, as is plain from what is said
of the natural characteristic of the serpent in the first verse
of the chapter (3:1), and from the curse pronounced upon the
animal itself. But that Satan was the actual tempter, and that
he used the serpent merely as his instrument, is evident (1)
from the nature of the transaction; for although the serpent may
be the most subtle of all the beasts of the field, yet he has
not the high intellectual faculties which the tempter here
displayed. (2.) In the New Testament it is both directly
asserted and in various forms assumed that Satan seduced our
first parents into sin (John 8:44; Rom. 16:20; 2 Cor. 11:3, 14;
Rev. 12:9; 20:2)." Hodge's System. Theol., ii. 127.
