Proverbs 17:2-4

Lexham English Bible

² A slave who deals wisely will rule over a child who acts shamefully,
    and in the midst of brothers he will share his inheritance.
³ A crucible is for the silver, and a furnace is for the gold,
    but Yahweh will test hearts.
⁴ He who does evil listens to lips of wickedness,
    and the liar gives heed to the tongue of mischief.
