When the soldiers had crucified Jesus, they took his garments and divided them into four parts, one part for each soldier; also his tunic. But the tunic was seamless, woven in one piece from top to bottom, (John 19:23 ESV)
As Jesus was hanging on the cross the Roman soldiers in charge of his death were dividing his clothes amongst themselves. They saved his tunic, probably the only valuable possession he had, for last. It was special, made from only one piece of material rather than a stitched together patchwork garment.
The symbolic nature of the pagan Romans acquiring Christ’s clothing is very interesting. Jesus is regularly referred to as the second Adam. God took the hides of animals and used them to clothe Adam and Eve after their initial sin.
Christ’s death and resurrection created a renewed opportunity for relationship with God. The New Testament writings at one point even mention that we wear the righteousness of Christ. Our sin is our own, but our righteousness is his. We have none. We, like the Romans who divided his clothes, are wrapped in his garments.
