v.9. “Soul shall be joyful”: the joy of deliverance, not joy in the destruction of others. Joy is in the salvation that God brings. v.10. “Bones shall say”: “Bones rejoice” [Ps.51:8]. He has been crushed; the frame that sustained him had given way. If God would intervene, he would rejoice. Only God can bring deliverance. Only God is there for the poor and downtrodden. Only God can save in power and can aid the hurting.
Psalm 35:9–10
