Matthew 27:28

And they stripped him
Of his clothes; at least of his upper garment: for one man to spit upon another, as these soldiers afterwards did on Christ, or to strip him of his garment, according to the Jewish canons, were punishable with a fine of four hundred pence ^F26, which amounted to twelve pounds and ten shillings of our money; but the soldiers were in no danger of being prosecuted, for stripping Christ. This is one part of the low estate Christ submitted to: his clothes on his back seem to be all he had in this world, and of these he is stripped:

and put on him a scarlet robe,
or "a red coat", as the Persic version renders it; very likely an old coat of one of their officers. The Evangelists Mark and John say it was "purple", ( Mark 15:17 ) ( John 19:2 ) , and so the Arabic version renders it here: whether there were two garments put upon him, the one a purple vest, and the other a scarlet robe over it; or whether scarlet was used instead of purple, is not certain; which was a colour wore by kings, and a sign of imperial dignity ^F1; and therefore put upon Christ by way of mockery, upbraiding him with the character he bore, as king of the Jews. This was an emblem of his being clothed, as it were with our sins, which are as scarlet, and of his bloody sufferings in the human nature.
