What does Psalm 22:15 mean?
Symbolically, David writes about weakness and severe dehydration when his enemies surrounded him—his plight is so traumatic that he feels near death. This continues his dramatic prayer during a time he felt abandoned by God (Psalm 22:1–2), which also serves as a prediction of Messiah's suffering (Matthew 27:46).A "potsherd" is a fragment of broken clay. The emphasis here is on "dryness," suggesting one whose strength has vanished like the water out of a piece of baked ceramic.
Jesus' strength left Him during the ordeal of His arrest and crucifixion. He was brutalized by Pilate's soldiers. They shoved a crown of thorns onto His head and beat Him with a reed (Matthew 27:27–30). This unusually brutal abuse left Jesus too weak to carry His cross all the way to Calvary. The soldiers compelled Simon, a man of Cyrene, to carry it (Matthew 27:32). In a severely weakened condition on the cross, Jesus died before the two robbers who were crucified alongside Him (John 19:31–33).
Even so, it's worth noting that Jesus died by an act of His will. He called out loudly and dismissed His spirit (Matthew 27:50; Luke 23:46; John 19:30). At one point in His earthly ministry Jesus affirmed: "For this reason the Father loves me, because I lay down my life that I may take it up again. No one takes it from me, but I lay it down of my own accord. I have authority to lay it down, and I have authority to take it up again" (John 10:17–18). It was only after He had fulfilled His mission to provide redemption that Jesus cried, "It is finished" (John 19:30) and dismissed His spirit.
Psalm 22:1–21 depicts David's questioning of God's silence and estrangement from him in his desperate situation. The structure of this prayer, and the images it evokes, are prophecies of Messiah's sufferings. Isaiah 53:3–8 likewise predicts these experiences and explains that Messiah endured them for us sinners. Matthew 27:46 reports that Jesus quoted Psalm 22:1 when he was suffering on the cross. First Peter 2:24 –25 refers to the sufferings of Jesus the Messiah and calls Jesus ''the Shepherd and Overseer of your souls.''
This psalm may be divided into two parts. The first part, verses 1–21, contains an urgent prayer, in which the suppliant questions a holy God's distance from him in his time of suffering. It also contains a graphic description of the Messiah's suffering. Messiah's suffering included humiliation, the taunts of unbelievers, a distressful sense of loneliness, and intense physical pain. The second part of the psalm continues a prayer to be delivered, and includes a glimpse of resurrection and exaltation. The psalm praises God and announces a future time when God will receive worldwide acclaim and worship.
