Proverbs 17:2-4 New Revised Standard Version, Anglicised (NRSVA)
2 A slave who deals wisely will rule over a child who acts shamefully,
and will share the inheritance as one of the family.
3 The crucible is for silver, and the furnace is for gold,
but the Lord tests the heart.
4 An evildoer listens to wicked lips;
and a liar gives heed to a mischievous tongue.
