Psalms 27:12

Deliver me not over unto the will of mine enemies - Let them not accomplish their desires in regard to me; let them not be able to carry out their purposes. The word here rendered “will” means properly “soul,” but it is used here evidently to denote “wish” or “desire.” Compare Psalms 35:25.

For false witnesses are risen up against me - People who would lay false charges against him, or who would wrongfully accuse him. They charged him with crimes which he never committed, and they persecuted him as if he were guilty of what they alleged against him.

And such as breathe out cruelty - That is, they meditate violence or cruel treatment. They are intent on this; they pant for it. Saul of Tarsus thus “breathed out threatenings and slaughter against the disciples of the Lord.” See the notes at Acts 9:1.
