A.T. Robertson Commentary John 19:5

"Jesus therefore came out, wearing the crown of thorns and the purple garment. And [Pilate] saith unto them, Behold, the man!" — John 19:5 (ASV)

Wearing (φορων). Present active participle of φορεω, an early frequentative of φερω, denoting a continual wearing, though not true here (only temporary). Jesus bore the mockery with kingly dignity as part of the shame of the Cross (Hebrews 12:2).

Behold, the man (Ιδου ο ανθρωπος). Ecce Homo! by Pilate. This exclamatory introduction of Jesus in mock coronation robes to the mob was clearly intended to excite pity and to show how absurd the charge of the Sanhedrin was that such a pitiable figure should be guilty of treason. Pilate failed utterly in this effort and did not dream that he was calling attention to the greatest figure of history, the Man of the ages.
