Therefore my heart rejoiced, and my soul exulted. My body also will dwell in safety.
Joy and security flow from the confidence expressed in the previous verse: the Lord is before him and at his right hand, therefore he will not be shaken. For this reason his heart rejoices, and his whole being exults. His joy does not depend only on favorable circumstances, but is born from the confidence that he is under God’s presence and protection. The words “My flesh also will dwell in security” show that this confidence concerns not only his inner world, but his whole person. As in the previous verse, here too these words have a prophetic meaning concerning Christ. Their prophetic meaning becomes especially clear from the next verse, where it is said that God will not allow His Holy One to see corruption. Therefore this confidence of David at the same time prefigures a greater reality, which finds its full fulfillment in Christ (Acts 2:25–31). With perfect confidence He entrusted Himself to the Father, and even in the face of death He knew that His body would not remain finally under the power of death. For this reason the joy and security of this verse receive their deepest meaning in Christ: death did not have final authority over Him.
