Proverbs 17:3-6

³The heating-pot is for silver and the oven-fire for gold, but the Lord is the tester of hearts.

⁴A wrongdoer gives attention to evil lips, and a man of deceit gives ear to a damaging tongue.

⁵Whoever makes sport of the poor puts shame on his Maker; and he who is glad because of trouble will not go free from punishment.

⁶Children's children are the crown of old men, and the glory of children is their fathers.
