I can count all my bones— they stare and gloat over me; they divide my garments among them, and for my clothing they cast lots. (Psalm 22:17, 18 ESV)
so they said to one another, “Let us not tear it, but cast lots for it to see whose it shall be.” This was to fulfill the Scripture which says, “They divided my garments among them, and for my clothing they cast lots.” So the soldiers did these things, (John 19:24 ESV)
One thousand years before the birth of Christ David foretold some explicit details of our savior's murder. He saw the nature of the bloody scourging which would leave him bloodied and exposed. He saw that the executioners would cast lots for the Messiah's clothing.
David was far from a perfect man or king, but he was called a "man after God's own heart." Not because of his perfection, but in-spite of his imperfections. David was a guy that had the ability to overcome his own hangups and follow God's will for his life. David wasn't perfect, but God used him to prophecy about the coming of another king—a perfect king.
David's prophecies came true. Jesus was scourged until his ribs and bones were exposed. It was horrible. He was killed on the cross, and his murderers gambled for his clothing. And while the specific details of Christ's death are gruesome and tragic, the end result is glorious, and beautiful. That God would use imperfect people to point ahead to the perfect one, sent to rescue us from our imperfection, is pretty incredible!
