Isaiah 52:14 NLT ‘Just as there were many who were appalled at him — his appearance was so disfigured beyond that of any human being and his form marred beyond human likeness–“

From what I have read is that the section 52 of Isaiah is a prophecy of the coming Messiah.

John Gill’s Exposition of the Whole Bible

“As many were astonished at thee,…. Not so much at the miracles he wrought, the doctrines he taught, and the work he did; or at his greatness and glory, at his exaltation and dignity, though very wonderful; as at his humiliation, the mean appearance he made, the low estate he was brought into; the sufferings and death which he underwent. These words are placed between the account of his exaltation and humiliation, and may be thought to have respect to both; and indeed it is astonishing that one so great as he was, and is, should become so low as he did; and also that one that was brought so low should be raised so high:

his visage was so marred more than any man, and his form more than the sons of men; though fairer than the children of men, as he was the immediate workmanship of the divine Spirit, and without sin; yet, what with his griefs and sorrows he bore, and troubles he met with; what with watchings and fastings, with laborious preaching, and constant travelling about to do good; what with sweat and blood, with buffetings and scourgings, never was any man’s face more marred, or his form more altered, than his was.”

Bibletools.org shows this mention of prophesy:

A mention of prophesy” “he prophet Isaiah prophesies how Jesus appeared after the scourging: “Just as many were astonished at you, so His visage [appearance, margin] was marred more than any man, and His form more than the sons of men” (Isaiah 52:14)
