Albert Barnes Commentary Psalms 18:48

"He rescueth me from mine enemies; Yea, thou liftest me up above them that rise up against me; Thou deliverest me from the violent man." — Psalms 18:48 (ASV)

He delivereth me from mine enemies - From all my foes.

Yea, thou liftest me up above those that rise up against me - So that I triumph over them. Instead of being subdued by them and trampled under their feet, I am exalted, and they are humbled.

Thou hast delivered me from the violent man - Margin, as in Hebrew, man of violence; the man characterized by injustice and wrong; the man who endeavored to overcome and subdue me by force and arms. There is probably a special allusion here by the psalmist to Saul as his great enemy, but perhaps he had also in his mind others of the same kind, and the meaning may be that he had been delivered from all of that class of people.
