Albert Barnes Commentary Psalms 69:29

"But I am poor and sorrowful: Let thy salvation, O God, set me up on high." — Psalms 69:29 (ASV)

But I am poor and sorrowful - I am afflicted and suffering. The word here rendered "poor" often means "afflicted."

Let thy salvation, O God, set me up on high - Let your help raise me up from my low condition, and exalt me to a place of safety.
