Psalm 12:6-8

Amplified Bible

⁶ 
The words and promises of the Lord are pure words,
Like silver refined in an earthen furnace, purified seven times.
⁷ 
You, O Lord, will preserve and keep them;
You will protect him from this [evil] generation forever.
⁸ 
The wicked strut about [in pompous self-importance] on every side,
As vileness is exalted and baseness is prized among the sons of men.
