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

“The getting--or, "what is obtained" (compare Job 7:2; Jer 22:13, Hebrew). vanity . . . to and fro--as fleeting as chaff or stubble in the wind (compare Pro 20:17-21; Psa 62:10). Such gettings are unsatisfactory. them . . . death--act as if they did (Pro 8:36; Pro 17:19).”
