Adam Clarke on Psalms 22:20

Deliver my soul from the sword - Deliver נפשי naphshi, my life; save me alive, or raise me again.

My darling - יחידתי yechidathi, my only one. The only human being that was ever produced since the creation, even by the power of God himself, without the agency of man. Adam the first was created out of the dust of the earth; that was his mother; God was the framer. Adam the second was produced in the womb of the virgin; that was his mother. But that which was conceived in her was by the power of the Holy Ghost; hence the man Christ Jesus is the Only Son of God; God is his Father, and he is his Only One.
