Proverbs 19:28

28 A worthless witness scoffeth at right; And the mouth of the godless swalloweth up mischief. The Mosaic law does not know the oath of witnesses; but the adjuring of witnesses to speak the truth, Lev 4:1, places a false statement almost in the rank of perjury. The משׁפּט, which legally and morally binds witnesses, is just their duty to state the matter in accordance with truth, and without deceitful and malicious reservation; but a worthless witness (vid., regarding בּליּעל, Pro 6:12) despiseth what is right (יליץ with accus.-obj. like Pro 14:9), i.e., scornfully disregards this duty. Under 28b Hitzig remarks that בלע only in Kal means to devour, but in Piel, on the contrary, to absorb = annihilate; therefore he reads with the lxx and Syr. דּין justice instead of און mischief: the mouth of the wicked murders that which is right, properly, swallows down his feeling of right. But בּלּע interchanges with בּלע in the sense of swallowing only, without the connected idea of annihilation; cf. כּבלּע for the continuance [duration] of a gulp = for a moment, Num 4:20 with Job 7:29; and one can thus understand 28b without any alteration of the text after Job 15:16; cf. Pro 20:12-15, as well as with the text altered after Isa 3:12, by no means so that one makes און the subject: mischief swallows up, i.e., destroys, the mouth of the wicked (Rashi); for when "mouth" and "to swallow" stand connected, the mouth is naturally that which swallows, not that which is swallowed (cf. Ecc 10:12 : the mouth of the fool swallows, i.e., destroys, him). Thus 28b means that wickedness, i.e., that which is morally perverse, is a delicious morsel for the mouth of the godless, which he eagerly devours; to practise evil is for him, as we say, "ein wahrer Genuss" [a true enjoyment].

Here is a description of the worst of sinners, whose hearts are fully set in them to do evil. 1. They set that at defiance which would deter and detain them from sin: An ungodly witness is one that bears false witness against his neighbour, and will forswear himself to do another a mischief, in which there is not only great injustice, but great impiety; this is one of the worst of men. Or an ungodly witness is one that profanely and atheistically witnesses against religion and godliness, whose instructions seduce from the words of knowledge (Pro 19:27); such a one scorns judgment, laughs at the terrors of the Lord, mocks at that fear, Job 15:26. Tell him of law and equity, that the scriptures and an oath are sacred things, and not to be jested with, that there will come a reckoning day; he laughs at it all, and scorns to heed it. 2. They are greedy, and glad of that which gives them an opportunity to sin: The mouth of the wicked eagerly devours iniquity, drinks it in like water, Job 15:16.
