Why the torn veil?

At that moment the curtain of the temple was torn in two from top to bottom. The earth shook and the rocks split. Matthew 27:51

The veil between the Holy place and the Most Holy place was a veil or a curtain that said, "Keep out!" Once a year, on the day of Atonement, the High Priest entered into the Holy of Holies with the blood of a sacrifice to make atonement for the sins of the people. It was a very solemn occasion and the high priest feared for his own life. On the fringes of his rove he had bells attached so that he could be heard outside the Holy of Holies as he moved about. Tradition has it that he also had a rope attached to his ankle so that if the offering was not accepted and he died in the presence of the Most Holy God that he could be dragged out rather than other priests going in for his body. This is only a tradition and has no Biblical support.
The veil was so heavy that it took thirty priests to hang it in place and it is said that thirty yoke of oxen could not tear it apart. However, when Jesus died the veil was torn in two from the top to the bottom. No one missed the significance of this. Man could not have done that, only something miraculous.
The veil that once said, "Keep out!" was now open and the invitation was to anyone to enter. The writer of Hebrews tells us that we can come boldly into God's presence. We can come boldly because of what Jesus did on the cross. The invitation is now open to all, "Come".
