Albert Barnes Commentary Psalms 35:10

"All my bones shall say, Jehovah, who is like unto thee, Who deliverest the poor from him that is too strong for him, Yea, the poor and the needy from him that robbeth him?" — Psalms 35:10 (ASV)

All my bones shall say - A similar expression occurs in (Psalms 51:8): That the bones which thou hast broken may rejoice. The “bones” are here put for the frame; the whole man. See the notes at (Psalms 32:3). The idea is that he had been crushed and overwhelmed with trouble and danger, so that his very frame—that which sustained him—had given way. He says now that if God would intervene in the manner for which he prays, he would be relieved of the unbearable burden, and his whole nature would rejoice.

Who is like unto thee - Who can bring deliverance like God? Compare the notes at (Isaiah 40:18): Which deliverest the poor, etc. This means, who rescues the poor from the hand of the mighty. That is:

1. Who is there that would intervene as God does on behalf of the poor and the downtrodden?
2. Who is there that could save them as He does? In His power, and in His willingness to aid, there is no one like God. The word rendered "poor" here rather means one who is afflicted, or crushed by trial.

Yea, the poor and the needy - The word here rendered "poor" is the same as that which occurs in the previous part of the sentence. The word rendered “needy” is that which is commonly used to denote the poor in the usual sense of the term—one who is in need. The reference is to David, who was afflicted by persecution, and at the same time was lacking the comforts of life.

From him that spoileth him - From him who would plunder and rob him.
