This obviously has reference to the mortal ministry of Jesus Christ. Jesus of Nazareth was scourged according to the Roman practice of scourging (Matt 27:26):
“Flogging was a legal preliminary to every Roman execution, and only women and Roman senators or soldiers (except in cases of desertion) were exempt. The usual instrument was a short whip…with several single or braided leather thongs of variable lengths, in which small iron balls or sharp pieces of sheep bones were tied at intervals…For scourging, the man was stripped of his clothing, and his hands were tied to an upright post. The back, buttocks, and legs were flogged either by two soldiers (lictors) or by one who alternated positions. The severity of the scourging depended on the disposition of lictors and was intended to weaken the victim to a state just short of collapse or death. After the scourging; the soldiers often taunted their victim.” (“On the Physical Death of Jesus Christ,” Journal of the American Medical Association, Mar. 1986, vol. 255, no. 11, p. 1457)
The phrase, ‘I hid not my face from shame and spitting’, is fulfilled twice. When Jesus was before Caiaphas and the Sanhedrin, he was spat upon. This happened again at the hands of the Roman soldiers:
’Then did they (the members of the Sanhedrin) spit in his face, and buffeted him; and others smote him with the palms of their hands,
Saying, Prophecy unto us, thou Christ, Who is he that smote thee?’ (Matt 26:67-68)
’And when they (the Roman soldiers) had platted a crown of thorns, they put it upon his head, and a reed in his right hand: and they bowed the knee before him, and mocked him, saying, Hail, King of the Jews!
And they spit upon him, and took the reed, and smote him on the head.’ (Matt 27:29-30)
