Treasury of Scripture
Mark 15:17 And they clothed him with purple, and platted a crown of thorns, and put it about his head,
Luke 23:11 And Herod with his men of war set him at nothing, and mocked him, and arrayed him in a gorgeous robe, and sent him again to Pilate.
John 19:2-5 And the soldiers platted a crown of thorns, and put it on his head, and they put on him a purple robe...
a scarlet robe. Mark calls it a purple robe; but by [porphura] is denoted whatever is of a dazzling red; and the words [kokkinos,] scarlet, and [porphura,] purple, are not infrequently interchanged.
