*Minor differences ignored. Grouped by changes, with first version listed as example.
They have sharpened their tongues like a serpent - Compare the notes at Psalm 64:3. The idea here is, that since the tongue of the serpent "seems" to be sharp, pointed, adapted to penetrate (and probably the original reference in the image was derived from that idea), the wound inflicted is by the serpent's tongue - "as if" with a hard, penetrating point. It is now known, however, that it is by a tooth - a single tooth, made flexible for the purpose - at the root of which a small bag containing the poison is located, which is injected through an orifice in the tooth into the wound. The meaning here is, that the words spoken by such persons - by their tongues - were like the poison produced by the bite of a serpent.
Adders' poison is under their lips - The asp or adder is among the most poisonous of serpents. Thus, Cleopatra of Egypt is said to have destroyed her own life by an asp, which she had concealed for that purpose. This passage is quoted in Romans 3:13, as a proof of human depravity. See the notes at that verse.
They have sharpened their tongues - They employ their time in forging lies and calumnies against me; and those of the most virulent nature.
They have sharpened their tongues like a serpent; (c) adders' poison [is] under their lips. Selah.
(c) He shows the weapons the wicked use, when power and force fail them.
They have sharpened their tongues like a serpent,.... Which Kimchi says it does before it bites. Aristotle (i) observes, that the tip or extreme point of a serpent's tongue is as small as a hair, and so exceeding sharp and piercing. Arama interprets this of the sharpness and cunning of the serpent; and particularly the serpent that deceived Eve, and spake cunningly to her. "For God knoweth", &c. and may design the calumnies and detractions, which were sharp as a razor; as swords, and spears, and arrows, and as the tongue of a serpent, Psalm 57:4; and the subtlety of false teachers, and deceitful workers; and the sharp and cutting words of wicked men against Christ and his people, Jde 1:15;
adder's poison is under their lips; which may signify the malignity of sin in wicked men, which comes from the old serpent the devil; is latent in men; very infectious, like poison, and deadly and incurable, but by the grace of God, and blood of Christ: and may describe particularly the mischief of the tongue, which is a little member, as the asp is a little creature; but very mischievous, full of deadly poison, which lurks in it, lies under it, and which spitting out, it stupifies and kills insensibly; as do the calumnies of wicked men, and the doctrines of false teachers; see Romans 3:13. The Targum is,
"the poison of the spider;''
though it is said (k) the spider is not venomous.
