Proverbs 17:3-5

Authorized (King James) Version

³ The fining pot is for silver, and the furnace for gold:
    but the Lord trieth the hearts.

⁴ A wicked doer giveth heed to false lips;
    and a liar giveth ear to a naughty tongue.

⁵ Whoso mocketh the poor reproacheth his Maker:
    and he that is glad at calamities shall not be unpunished.
