Their throat ... - This expression is taken from Psalm 5:9, literally from the Septuagint. The design of the psalm is to reprove those who were false, traitorous, slanderous, etc. Psalm 5:6. The psalmist has the sin of deceit, and falsehood, and slander particularly in his eye. The expressions here are to be interpreted in accordance with that. The sentiment here may be, as the grave is ever open to receive all into it, that is, into destruction, so the mouth or the throat of the slanderer is ever open to swallow up the peace and happiness of all. Or it may mean, as from an open sepulchre there proceeds an offensive and pestilential vapor, so from the mouths of slanderous persons there proceed noisome and ruinous words. "(Stuart.)" I think the connection demands the former interpretation.

With their tongues ... - In their conversation, their promises, etc., they have been false, treacherous, and unfaithful.

The poison of asps - This is taken literally from the Septuagint of Psalm 140:3. The asp, or adder, is a species of serpent whose poison is of such active operation that it kills almost the instant that it penetrates, and that without remedy. It is small, and commonly lies concealed, often in the "sand" in a road, and strikes the traveler before he sees it. It is found chiefly in Egypt and Lybia. It is said by ancient writers that the celebrated Cleopatra, rather than be carried a captive to Rome by Augustus, suffered an asp to bite her in the arm, by which she soon died. The precise species of serpent which is here meant by the psalmist, however, cannot be ascertained. All that is necessary to understand the passage is, that it refers to a serpent whose bite was deadly, and rapid in its execution.

Is under their lips - The poison of the serpent is contained in a small bag which is concealed at the root of the tooth. When the tooth is struck into the flesh, the poison is pressed out, through a small hole in the tooth, into the wound. Whether the psalmist was acquainted with that fact, or referred to it, cannot be known: his words do not of necessity imply it. The sentiment is, that as the poison of the asp is rapid, certain, spreading quickly through the system, and producing death; so the words of the slanderer are deadly, pestiferous, quickly destroying the reputation and happiness of man. They are as subtle, as insinuating, and as deadly to the reputation, as the poison of the adder is to the body. Wicked people in the Bible are often compared to serpents; Matthew 23:33; Genesis 49:17.

Their throat is an open sepulchre - This and all the following verses to the end of the 18th are found in the Septuagint, but not in the Hebrew text; and it is most evident that it was from this version that the apostle quoted, as the verses cannot be found in any other place with so near an approximation to the apostle's meaning and words. The verses in question, however, are not found in the Alexandrian MS. But they exist in the Vulgate, the Ethiopic, and the Arabic. As the most ancient copies of the Septuagint do not contain these verses, some contend that the apostle has quoted them from different parts of Scripture; and later transcribers of the Septuagint, finding that the 10th, 11th, and 12th, verses were quoted from the xivth Psalm, imagined that the rest were found originally there too, and so incorporated them in their copies, from the apostle's text.

Their throat is an open sepulchre - By their malicious and wicked words they bury, as it were, the reputation of all men. The whole of this verse appears to belong to their habit of lying, defamation, slandering, etc., by which they wounded, blasted, and poisoned the reputation of others.

Their throat is an open sepulchre,.... The several vices of the instruments of speech are here, and in the following verse, exposed: "the throat" is said to "be an open sepulchre", as in Psalm 5:9, so called, for its voracity and insatiableness; both as an instrument of speech, for the words of the wicked are devouring ones; and as an instrument of swallowing, and so may denote the sinner's eager desire after sin, the delight and pleasure he takes in it, the abundance of it he takes in, and his insatiable greediness for it; likewise for its filthy stench, the communication of evil men being corrupt; and because, as by an open grave, persons may fall unawares to their hurt, so the evil communications of wicked men, as they corrupt good manners, are dangerous and hurtful: R. Aben Ezra explains it by , "immediate destruction", or sudden death:

with their tongues they have used deceit; which may design the sin of flattery, for the words in Psalm 5:9; the place referred to, are, "they flatter with their tongue"; either God or men, themselves or others, their princes or their neighbour; for there are flatterers in things sacred and civil, there are self-flatterers, court flatterers, and flattering preachers, and all abominable and mischievous; or the phrase may design the sin of lying, either politically, officiously, perniciously, and religiously; and in this latter way, either with respect to doctrine or practice:

the poison of asps is under their lips; or as in Psalm 140:3, "adders' poison is under their lips". The asp is but a small creature, and so is the tongue, James 3:5, but there is a world of mischief in it, signified by poison; which, as that, is latent and secret, is under it; and as that stupefies and kills insensibly, so an evil tongue does, and that in a deadly and incurable manner: oftentimes the Jews speak of the evil imagination, or corruption of nature entering into persons, and operating in them, "as poison in an angry serpent" (w).

(w) T. Bab. Sabbat, fol. 62. 2. Yoma, fol. 9. 2.

Open sepulchre (τάφος ἀνεῳγμένος)

Lit., a sepulchre opened or standing open. Some explain the figure by the noisome exhalations from a tomb. Others refer it to a pit standing open and ready to devour, comparing Jeremiah 5:16, where the quiver of the Chaldaeans is called an open sepulchre. So Meyer and Morison. Godet compares the phrase used of a brutal man: "it seems as if he would like to eat you." Compare Dante's vision of the lion:

"With head uplifted and with ravenous hunger,

So that it seemed the air was afraid of him."

"Inferno," i., 47.

Have used deceit (εδολιουσαν)

Hebrew, they smoothed their tongues. Guile is contrasted with violence in the previous clause. Wyc., with their tongues they did guilingly. The imperfect tense denotes perseverance in their hypocritical professions.

Their throat is an open sepulchre; with their tongues they have used deceit; the poison of asps is under their lips:

3:13 Their throat is an open sepulchre. Thus far the statements have been general. Now we come to particulars. If the grave is opened, corruption is manifest. So corruption comes from the throats of men when they speak.

The poison of asps. The venom of falsehood, as deadly as the deadly serpent.

3:13 Their throat - Is noisome and dangerous as an open sepulchre. Observe the progress of evil discourse, proceeding out of the heart, through the throat, tongue, lips, till the whole mouth is filled therewith. The poison of asps - Infectious, deadly backbiting, tale - bearing, evil - speaking, is under (for honey is on) their lips. An asp is a venomous kind of serpent. Psalm 5:9; Psalm 140:3.

13-18. Their, &c.-From generals, the apostle here comes to particulars, culling from different parts of Scripture passages which speak of depravity as it affects the different members of the body; as if to show more affectingly how "from the sole of the foot even to the head there is no soundness" in us.

throat is an open sepulchre-(Ps 5:9); that is, "What proceeds out of their heart, and finds vent in speech and action through the throat, is like the pestilential breath of an open grave."

with their tongues they have used deceit-(Ps 5:9); that is, "That tongue which is man's glory (Ps 16:9; 57:8) is prostituted to the purposes of deception."

the poison of asps is under their lips-(Ps 140:3): that is, "Those lips which should 'drop as an honeycomb,' and 'feed many,' and 'give thanks unto His name' (So 4:11; Pr 10:21; Heb 13:15), are employed to secrete and to dart deadly poison."

3:9-18 Here again is shown that all mankind are under the guilt of sin, as a burden; and under the government and dominion of sin, as enslaved to it, to work wickedness. This is made plain by several passages of Scripture from the Old Testament, which describe the corrupt and depraved state of all men, till grace restrain or change them. Great as our advantages are, these texts describe multitudes who call themselves Christians. Their principles and conduct prove that there is no fear of God before their eyes. And where no fear of God is, no good is to be looked for.
