John Gill, on Prov 21:6

“He that gathereth treasures by a lying tongue, is vain and foolish, and shall stumble upon the snares of death.”

“The getting of treasures by a lying tongue,.... By telling lies in trade; by bearing false witness in a court of judicature; or by preaching false doctrines in the church of God: is a vanity tossed to and fro of them that seek death: such treasures, though ever so great, are like any light thing, smoke or vapour, straw, stubble, chaff, or a feather, tossed about the wind; which is expressive of the instability uncertainty of riches ill gotten; they do not last long, but are taken away and carried off by one providence or another; and they are likewise harmful and pernicious; they issue in death: and those that seek after them, and obtain them in a bad way, are said to "seek death": not intentionally, but eventually; this they certainly find, if grace prevent not; see Pro 8:36. Jarchi reads it, they are the "snares of death" to him; and so the Septuagint version.”
