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 that 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.” 

Why did God rip the second veil open when Jesus died? Because the Most Holy room of the Temple symbolized heaven. When Jesus died, he paid the ransom price for sin and opened access to God through His blood. 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”.

 

The first Passover included several types

the Pascal lamb  = Jesus, 

the first-born spared from death = the church of the first-born,

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.  Anti-typically, 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.”

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