Luke 23:34

And Jesus said, Father, forgive them: for they know not what they do. And parting his garments among them, they cast lots.

Father, forgive them, etc. ... This was the first of the seven utterances of Jesus from the cross; and it has the utility of indicating two centers of forgiveness, one on the earth, the other in heaven. It may not be supposed that Jesus' prayer for the forgiveness of the soldiers who crucified him implied their immediate forgiveness in heaven. Jesus, AS A MAN, forgave them; but the matter of their eternal forgiveness was still contingent upon their faith and acceptance of the terms of the Christian gospel. See full discussion of this under "The Seven Words from the Cross," in my Commentary on Matthew, Matthew 27:66.

And parting his garments among them, they cast lots ... As Barclay noted:

Every Jew wore five articles of apparel: the inner tunic, the outer robe, the girdle, the sandals, and the turban. There remained the great outer robe. It was woven in one piece (John 19:23,24). To cut it would have ruined it; and so the soldiers gambled for it.[20]

For further discussion of this action of the soldiers in fulfillment of prophecy, and regarding the garments of Jesus, see in my Commentary on John, under John 19:24. The prophecy fulfilled was Psalms 22:18.
