serpent

Concise Bible Dictionary:

The Hebrew word most commonly translated serpent is nachash, agreeing with ὅφις in the New Testament, so called because of its “hissing.” These words are used for the serpent that beguiled Eve (Gen. 3:1-141Now the serpent was more subtile than any beast of the field which the Lord God had made. And he said unto the woman, Yea, hath God said, Ye shall not eat of every tree of the garden? 2And the woman said unto the serpent, We may eat of the fruit of the trees of the garden: 3But of the fruit of the tree which is in the midst of the garden, God hath said, Ye shall not eat of it, neither shall ye touch it, lest ye die. 4And the serpent said unto the woman, Ye shall not surely die: 5For God doth know that in the day ye eat thereof, then your eyes shall be opened, and ye shall be as gods, knowing good and evil. 6And when the woman saw that the tree was good for food, and that it was pleasant to the eyes, and a tree to be desired to make one wise, she took of the fruit thereof, and did eat, and gave also unto her husband with her; and he did eat. 7And the eyes of them both were opened, and they knew that they were naked; and they sewed fig leaves together, and made themselves aprons. 8And they heard the voice of the Lord God walking in the garden in the cool of the day: and Adam and his wife hid themselves from the presence of the Lord God amongst the trees of the garden. 9And the Lord God called unto Adam, and said unto him, Where art thou? 10And he said, I heard thy voice in the garden, and I was afraid, because I was naked; and I hid myself. 11And he said, Who told thee that thou wast naked? Hast thou eaten of the tree, whereof I commanded thee that thou shouldest not eat? 12And the man said, The woman whom thou gavest to be with me, she gave me of the tree, and I did eat. 13And the Lord God said unto the woman, What is this that thou hast done? And the woman said, The serpent beguiled me, and I did eat. 14And the Lord God said unto the serpent, Because thou hast done this, thou art cursed above all cattle, and above every beast of the field; upon thy belly shalt thou go, and dust shalt thou eat all the days of thy life: (Genesis 3:1‑14); 2 Cor. 11:33But I fear, lest by any means, as the serpent beguiled Eve through his subtilty, so your minds should be corrupted from the simplicity that is in Christ. (2 Corinthians 11:3)), and in other passages where Satan is alluded to (Isa. 27:11In that day the Lord with his sore and great and strong sword shall punish leviathan the piercing serpent, even leviathan that crooked serpent; and he shall slay the dragon that is in the sea. (Isaiah 27:1); Rev. 12:9-159And the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him. 10And I heard a loud voice saying in heaven, Now is come salvation, and strength, and the kingdom of our God, and the power of his Christ: for the accuser of our brethren is cast down, which accused them before our God day and night. 11And they overcame him by the blood of the Lamb, and by the word of their testimony; and they loved not their lives unto the death. 12Therefore rejoice, ye heavens, and ye that dwell in them. Woe to the inhabiters of the earth and of the sea! for the devil is come down unto you, having great wrath, because he knoweth that he hath but a short time. 13And when the dragon saw that he was cast unto the earth, he persecuted the woman which brought forth the man child. 14And to the woman were given two wings of a great eagle, that she might fly into the wilderness, into her place, where she is nourished for a time, and times, and half a time, from the face of the serpent. 15And the serpent cast out of his mouth water as a flood after the woman, that he might cause her to be carried away of the flood. (Revelation 12:9‑15); Rev. 20:22And he laid hold on the dragon, that old serpent, which is the Devil, and Satan, and bound him a thousand years, (Revelation 20:2)). SERPENT (COBRA).
The Lord bade His disciples be as wise as serpents, probably an allusion to Genesis 3:11Now the serpent was more subtile than any beast of the field which the Lord God had made. And he said unto the woman, Yea, hath God said, Ye shall not eat of every tree of the garden? (Genesis 3:1). The word “subtle” there is translated by the same word in the LXX as used in this passage. It is “prudence.”
