Proverbs 26:21-23

Lexham English Bible

²¹ As charcoal is to hot embers and wood is to fire,
    so a man of quarrels is to kindling strife.
²² The words of a whisperer are like delicious morsels,
    and they go down to the inner parts of the body.
²³ Like impure silver^[a] which overlays an earthen vessel,
    so are smooth lips and an evil heart^[b].
