Psalm 12:6

And the words of the LORD are flawless, like silver refined in a furnace of clay, purified seven times.
耶和华的言语是纯净的言语，如同银子在泥炉中炼过七次。

Indeed! His words are "flawless". You can read His words over and over again and still see that they remain true and firm. His words can undergo tribulations and guide you through whatever circumsances only to let you feel and know it's truth and substantiallity more and more, "like silver refined in a furnace of clay, purified seven times."
