There are no scriptures which record a knife falling from the priest’s hand at the moment of Jesus’ death.

Jesus fulfilled the whole Law. Luke 24:44 (ESV), “Then he (Jesus) said to them, These are my words that I spoke to you while I was still with you, that everything written about me in the Law of Moses and the Prophets and the Psalms must be fulfilled.”

Therefore, Jesus needed to die at the same time the Law required the Passover lamb to be sacrificed. The Apostle Paul specifically identified Jesus as the antitypical Passover lamb. 1 Corinthians 5:7 (ESV), “Cleanse out the old leaven that you may be a new lump, as you really are unleavened. For Christ, our Passover lamb, has been sacrificed.” 

Matthew 27:51, “And, behold, the veil of the temple was rent in twain from the top to the bottom; and the earth did quake, and the rocks rent.” 

Why did God rip the second veil open when Jesus died? Because the Most Holy room of the Temple symbolized heaven, the place where God’s justice could be satisfied. When Jesus died, he paid the ransom price for sin and opened access to God through his blood for both the church (his most faithful followers promised a heavenly reward) and the rest of the world (who will be raised from the dead, on earth).  After his resurrection and ascension, believers could then be called with a heavenly calling to be resurrected in heaven. Hebrews 10:19-20 (ESV), “Therefore, brothers, since we have confidence to enter the holy places by the blood of Jesus, by the new and living way that he opened for us through the curtain, that is, through his flesh.”

In the Old Testament are many events which actually happened but which have significance above and beyond their original import. For example: Exodus describes the institution of the Passover which involved the slaying of a lamb, the deliverance of the firstborn at night, and the deliverance of the rest of the people in the morning. The miracle would have been great in itself. But in 1 Corinthians 5:7 Paul states, “Christ, our Passover, is sacrificed for us,” indicating that God meant to make an informative picture of the Passover event.” The Passover in Exodus was a “type.” The “antitype” – the fulfillment of that original picture – was Jesus as our Passover lamb. The first Passover included several additional types, and it is encouraging to have so many Christian lessons come from the original Passover. Please see the Additional Resource below.

the Pascal lamb = Jesus, 

the first-born spared from death = the church of the first-born/the faithful followers of Jesus

the nation of Israel = the world of mankind

Egypt = Satan’s dominion of sin and death. 

Israel was delivered from Egyptian bondage in the morning after the firstborn were passed over by the angel of death. This was a picture of “antitype” of what would happen in the future: After the church of the firstborn (Hebrews 12:23) is “passed over,” the world of mankind will be delivered from Satan’s dominion of sin and death. Yes, in the Millennial morning of Christ’s 1,000-year reign, the blood of Jesus, the Pascal lamb, will deliver the whole world. 1 John 2:2 (ESV), “He is the propitiation for our sins, and not for ours only but also for the sins of the whole world.”
