Preserved And Kept Safe

Psalm 12:5-8
 
5  For the oppression of the poor, for the sighing of the needy, now will I arise, saith the LORD; I will set him in safety from him that puffeth at him. 
6  The words of the LORD are pure words: as silver tried in a furnace of earth, purified seven times. 
7  Thou shalt keep them, O LORD, thou shalt preserve them from this generation for ever. 
8  The wicked walk on every side, when the vilest men are exalted.
