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. says:

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.” 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)
