Psalms 12:8 ASV

⁶  The words of Jehovah are pure words; As silver tried in a furnace on the earth, Purified seven times.

⁷  Thou wilt keep them, O Jehovah, Thou wilt preserve them from this generation for ever.

⁸  The wicked walk on every side, When vileness is exalted among the sons of men. Psalm 13 For the Chief Musician. A Psalm of David.
