Psalm 12:6-8

American Standard Version

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.
