4 hours is much too generous...Joseph came to ask permission of Pilate when it was already evening...and it still had to be verified...
Try walking 3 mph during rush hour on a annual high holiday...much less get an appointment with the courts late on TGIF...lol
Besides that is your issue only if it must be done by sundown when the new day begins...
Seeing as a meal had to be prepared and eaten in their homes that evening...who would be left to take down dead bodies to prevent them hanging overnight? That was forbidden...
Mathew 27 states Jesus died around 3pm:
45From noon until three in the afternoon darkness came over all the land. 46About three in the afternoon Jesus cried out in a loud voice, “Eli, Eli,c lemasabachthani?” (which means “My God, my God, why have you forsaken me?”). 47When some of those standing there heard this, they said, “He’s calling Elijah.” 48Immediately one of them ran and got a sponge. He filled it with wine vinegar, put it on a staff, and offered it to Jesus to drink. 49The rest said, “Now leave him alone. Let’s see if Elijah comes to save him.” 50And when Jesus had cried out again in a loud voice, he gave up his spirit. 51At that moment the curtain of the temple was torn in two from top to bottom. The earth shook, the rocks split 52and the tombs broke open. The bodies of many holy people who had died were raised to life. 53They came out of the tombs after Jesus’ resurrection and went into the holy city and appeared to many people. 54When the centurion and those with him who were guarding Jesus saw the earthquake and all that had happened, they were terrified, and exclaimed, “Surely he was the Son of God!”
John 19 states that the Jewish leaders had the legs broken before Joseph of Arimathea went to Pilate (the video says it was the other way around?):
30When he had received the drink, Jesus said, “It is finished.” With that, he bowed his head and gave up his spirit. 31Now it was the day of Preparation, and the next day was to be a special Sabbath. Because the Jewish leaders did not want the bodies left on the crosses during the Sabbath, they asked Pilate to have the legs broken and the bodies taken down. 32The soldiers therefore came and broke the legs of the first man who had been crucified with Jesus, and then those of the other. 33But when they came to Jesus and found that he was already dead, they did not break his legs. 34Instead, one of the soldiers pierced Jesus’ side with a spear, bringing a sudden flow of blood and water. 35The man who saw it has given testimony, and his testimony is true. He knows that he tells the truth, and he testifies so that you also may believe. 36These things happened so that the scripture would be fulfilled: “Not one of his bones will be broken,”c 37and, as another scripture says, “They will look on the one they have pierced.”d
38Later, Joseph of Arimathea asked Pilate for the body of Jesus. Now Joseph was a disciple of Jesus, but secretly because he feared the Jewish leaders. With Pilate’s permission, he came and took the body away. 39He was accompanied by Nicodemus, the man who earlier had visited Jesus at night. Nicodemus brought a mixture of myrrh and aloes, about seventy-five pounds.e 40Taking Jesus’ body, the two of them wrapped it, with the spices, in strips of linen. This was in accordance with Jewish burial customs. 41At the place where Jesus was crucified, there was a garden, and in the garden a new tomb, in which no one had ever been laid. 42Because it was the Jewish day of Preparation and since the tomb was nearby, they laid Jesus there.
Mark 15 confirms that the centurion had already checked that Jesus was dead by the time Joseph asked Pilate:
44Pilate was surprised to hear that he was already dead. Summoning the centurion, he asked him if Jesus had already died. 45When he learned from the centurion that it was so, he gave the body to Joseph. 46So Joseph bought some linen cloth,
Luke 23 also confirms that although evening was approaching when Joseph went to ask Pilate it shows that He had laid Jesus in the tomb before the Sabbath began and that the women watch this and they also prepared the spices when they went home:
50Now there was a man named Joseph, a member of the Council, a good and upright man, 51who had not consented to their decision and action. He came from the Judean town of Arimathea, and he himself was waiting for the kingdom of God. 52Going to Pilate, he asked for Jesus’ body. 53Then he took it down, wrapped it in linen cloth and placed it in a tomb cut in the rock, one in which no one had yet been laid. 54It was Preparation Day, and the Sabbath was about to begin. 55The women who had come with Jesus from Galilee followed Joseph and saw the tomb and how his body was laid in it. 56Then they went home and prepared spices and perfumes. But they rested on the Sabbath in obedience to the commandment.
Sunset was around 7pm according to that time of year so this gave Joseph of Arimathea about 4 hours to go to Pilate, ask for the body, hear the centurion confirm Jesus had died, buy the linen (while Nicodemus bought the spices), go to the cross, take Jesus down, wash His Body, put the spices on, wrap Him in the shroud and lay Him in the tomb. The distance from Herods Palace to the Garden Tomb is less than 800 meters in a straight line but even doubling this would only take about 20 minutes to walk, at about 3 mph which I can easily do even when it's a busy shopping day in town.
So 4 hours is more than enough time to do all of this before sunset and the bodies had be at least taken down before the sunset because this was when the Sabbath was about to begin.
