Albert Barnes Commentary Psalms 141:8

"For mine eyes are unto thee, O Jehovah the Lord: In thee do I take refuge; leave not my soul destitute." — Psalms 141:8 (ASV)

But mine eyes are unto thee, O God the Lord - My hope is in you. I do not rely on my own power. I do not trust in my armed forces. I know that they are weak, dispirited, scattered—like strewn bones—like the chips and splinters lying around the place where wood is chopped. I look, therefore, solely to God. I believe that he will interpose; and now that my enemy has placed himself in this position, I do not need to resort to underhanded tactics—to dishonorable acts—to assassination—as my friends advise, but the object will be accomplished, and I will be placed on the throne by the act of God, and in a manner that will not subject my name and memory to reproach by a base and treacherous deed.

In thee is my trust - I rely on you alone.

Leave not my soul destitute - My life; my all. Do not now leave me without your gracious interposition; do not allow this critical moment to pass by without such an interposition as will end the war, and restore peace to me and to a troubled land.
