1 Enoch 62:5–7 — R. H. Charles (1917), public domain (public domain)
5. And one portion of them shall look on the other, And they shall be terrified, And they shall be downcast of countenance, And pain shall seize them, When they see that Son of Man Sitting on the throne of his glory.
And the kings and the mighty and all who possess the earth shall bless and glorify and extol him who rules over all, who was hidden.
For from the beginning the Son of Man was hidden, And the Most High preserved him in the presence of His might, And revealed him to the elect.

Why Pitre cites it
'For the offspring of the mother of the living was concealed from the beginning' — the Messiah as Eve's offspring, hidden with God: Pitre's proof that the Protoevangelium is Jewish soil.
Notes
Both key phrases present (the first across line breaks). Verse 6 reads 'him who rules over all, who was hidden'; verse 7 'For from the beginning the Son of Man was hidden'.
