Now it was the Preparation Day of the Passover, and about the sixth hour.
John 19:14a

Jerusalem swelled with pilgrims for the Passover. The sacrifice of lambs had to start early in the morning to complete them all by sundown. The final offering would be slaughtered at the ninth hour, a little before 3 p.m.

Now when the sixth hour had come, there was darkness over the whole land until the ninth hour. And at the ninth hour Jesus cried out with a loud voice, saying, "Eloi, Eloi, lama sabachthani?" which is translated, "My God, My God, why have You forsaken Me?"

Some of those who stood by, when they heard that, said, "Look, He is calling for Elijah!" Then someone ran and filled a sponge full of sour wine, put it on a reed, and offered it to Him to drink, saying, "Let Him alone; let us see if Elijah will come to take Him down."

And Jesus cried out with a loud voice, and breathed His last.
Mark 15:33-37

There, between the two colleagues of Bar-Abbas, Christ cried out, "It is finished." (John 19:30)

And in the temple, the priests blew the shofar. The final sacrifice, the Lamb for the nation, had been slain.

For the law, having a shadow of the good things to come, and not the very image of the things, can never with these same sacrifices, which they offer continually year by year, make those who approach perfect. For then would they not have ceased to be offered? For the worshipers, once purified, would have had no more consciousness of sins. But in those sacrifices there is a reminder of sins every year. For it is not possible that the blood of bulls and goats could take away sins.

Therefore, when He came into the world, He said:

"Sacrifice and offering You did not desire,
But a body You have prepared for Me.
In burnt offerings and sacrifices for sin
You had no pleasure.
Then I said, "Behold, I have come--
In the volume of the book it is written of Me--
To do Your will, O God."'

Previously saying, "Sacrifice and offering, burnt offerings, and offerings for sin You did not desire, nor had pleasure in them" (which are offered according to the law), 9then He said, "Behold, I have come to do Your will." He takes away the first that He may establish the second. By that will we have been sanctified through the offering of the body of Jesus Christ once for all.

And every priest stands ministering daily and offering repeatedly the same sacrifices, which can never take away sins. But this Man, after He had offered one sacrifice for sins forever, sat down at the right hand of God, from that time waiting till His enemies are made His footstool. For by one offering He has perfected forever those who are being sanctified.

But the Holy Spirit also witnesses to us; for after He had said before,
"This is the covenant that I will make with them after those days, says the LORD: I will put My laws into their hearts, and in their minds I will write them," then He adds, "Their sins and their lawless deeds I will remember no more." Now where there is remission of these, there is no longer an offering for sin.

Therefore, brethren, having boldness to enter the Holiest by the blood of Jesus, by a new and living way which He consecrated for us, through the veil, that is, 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, having our hearts sprinkled from an evil conscience and our bodies washed with pure water. Let us hold fast the confession of our hope without wavering, for He who promised is faithful. And let us consider one another in order to stir up love and good works, not forsaking the assembling of ourselves together, as is the manner of some, but exhorting one another, and so much the more as you see the Day approaching.
Hebrews 10:1-25
