How did the Sabbath explain why Jesus' body had to be taken down?

[tonychanyt]

Ex 20:

10a The seventh day is a Sabbath to the Lord your God. On it you shall not do any work.

De 21:

22 If a man has committed a sin worthy of death, and he is executed, and you hang his body on a tree, 23a you must not leave the body on the tree overnight, but you must be sure to bury him that day.

Jn 19:

31 Since it was the day of Preparation, and so that the bodies would not remain on the cross on the Sabbath (for that Sabbath was a high day), the Jews asked Pilate that their legs might be broken and that they might be taken away.

These Jews wanted to make sure that the three people on the crosses were dead and buried before the Sabbath. If they died on the Sabbath, they would have to be buried on the Sabbath day, according to Deuteronomy.

Babylonian Talmud, Shabbat 151a permits certain preparatory burial activities on Sabbath. Jerusalem Talmud, Berakhot 3:1 mentions postponing burial until after the Sabbath.

How did the Sabbath explain why Jesus' body had to be taken down?

It didn't. It was an excuse for the Jews to make sure that they died before the Sabbath.

32 So the soldiers came and broke the legs of the first, and of the other who had been crucified with him. 33 But when they came to Jesus and saw that he was already dead, they did not break his legs.

De 21:23 explained why Jesus' body had to be taken down before sunset. Ex 20:10 Sabbath law explained why Joseph of Arimathea and Nicodemus were in a hurry to bury Jesus's body and the women had to anoint the body of Jesus after the Sabbath.
