Earth-shaking Events Earth-shaking events regarding the Temple did not go unnoticed in Jewish literature, even though the torn-veil is not mentioned. These, according to the Jewish literature, happened 40 years before the Destruction of Jerusalem. (=30 A.D.)
(1) The Door of the Temple proper opened of its own accord, mysteriously.
(2) The lot for the scapegoat appeared in the different hand than was customary, when drawn out by lots.
(3) The Sanhedrin had to begin meeting in a different place than the Temple mount (earthquake damage?).
(4) The continuously-burning light on the Temple mount that was used to light all the other ("campus" lights there) was extinguished! The Temple was shrouded in darkness.
(5)The power of "capital punishment" was taken away.
The inner Curtain (Veil) of the Holy of Holies being torn would not have been seen by the normal, outer court worshippers since only the High Priest was allowed in there once a year on the Day of Atonement much later in the year (appx. September). The Passover (crucifixion) happened in April (approximately).
There were enough number of traumatic events openly experienced to let the Jews know something tragic was happening. Even though the torn veil wasn't one of them listed as noticed.
[Jerusalem Talmud, Jacob Neusner, The Yerushalmi, p. 156-157; Babylonian Talmud, Soncino version, Yoma 39b]
Addendum Consider how embarrassing it would be to the rabbis and high priest when they became aware of such a horrendous breach of the veil that revealed NO Shekinah Glory shining in there (representing No Presence of God).
Jesus High Priest Since there is now no more physical Temple nor physical Holy of Holies, a physical veil is of no consequence, whole or torn. But spiritually, believers do still have a precious Day of Atonement every day, with a High Priest interceding for us!
Having therefore, brothers, boldness to enter into the Holiest by the blood of Jesus, by a new and living way---which He has consecrated for us through the veil, that is to say, His flesh---and having a High Priest over the House of God, let us draw near with a true heart in full assurance of faith... (Hebrews 10:19-22)
