Then the soldiers, when they had crucified Jesus, took his garments, and made four parts, to every soldier a part; and also his coat: now the coat was without seam, woven from the top throughout.
All Commentaries on John 19:23 Go To John 19
John Chrysostom
AD 407
The Evangelist describes the tunic, to show that it was of an inferior kind, the tunics commonly worn in Palestine being made of two pieces.
Behold the sureness of prophecy. The Prophet foretold not only what they would part, but what they would not. They parted the raiment, but cast lots for the vesture.
According to some, The tunic without seam, woven from above throughout, is an allegory strewing that He who was crucified was not simply man, but also had Divinity from above.
