It is to be noted that the psalm says no more about the sins of unjust authorities, but passes on to describe the "wicked" generally. The transition may suggest that under unjust rulers all wrongdoers find impunity, and so multiply and worsen; or it may simply be that these former are now merged in the class to which they belong. The type of "wickedness" gibbeted is the familiar one of malicious calumniators and persecutors. From birth onwards they have continuously been doers of evil. The psalmist is not laying down theological propositions about heredity, but describing the inveterate habit of sin which has become a second nature, and makes amendment hopeless. The reference to "lies" naturally suggests the image of the serpent's poison. An envenomed tongue is worse than any snake's bite. And the mention of the serpent stimulates the poet's imagination to yet another figure, which puts most graphically that disregard of warnings, entreaties, and every voice, human or Divine, that marks long-practised, customary sinfulness. There can be no more striking symbol of determined disregard to the calls of patient Love and the threats of outraged Justice than that of the snake lying coiled, with its head in the centre of its motionless folds, as if its ears were stopped by its own bulk, while the enchanter plays his softest notes and speaks his strongest spells in vain. There are such men, thinks this psalmist. There are none whom the mightiest spell, that of God's love in Christ, could not conquer and free from their poison; but there are such as will close their ears to its plaintive sweetness. This is the condemnation that light is come and men love darkness, and had rather lie coiled in their holes than have their fangs extracted.
