Acquiring treasures by a lying tongue
is a fleeting vapor of those who seek death. Bible see other translations

“they seek death.” People who seek to “get ahead” and lie to get treasures of money and power think that they will be well off for their efforts. They won’t, although they do not know it, they are only seeking their own everlasting death. The truly wealthy may be poor in this life, but God will fulfill His promise of everlasting rewards to those who are godly and faithful to Him.
