(Deut. 21:22-23)22 When someone is convicted of a crime punishable by death and is executed, and you hang him on a tree, 23 his corpse must not remain all night upon the tree; you shall bury him that same day, for anyone hung on a tree is under God’s curse. You must not defile the land that the Lord your God is giving you for possession.
To quote this verse in Gal 3:13 makes very well the theological point of Paul (not only of an hypothetical Jewish Paul, but also of an hypothetical Gnostic Paul), BUT ONLY if Jesus is buried not the same day of the his crucifixion (the reason is clear: otherwise the ''land'' is not purified by the magic blood of Jesus).
But could that same verse be quoted by the Pillars of Jerusalem?
If the answer is ''yes'', then that verse is surely the unique verse in all the previous scripture (unless the real source is the original AoI) that could have inspired the Jewish Peter to imagine the idea of a crucified Christ.
This is possible only if you read the verse with glasses coloured of ''antithesis'': if the crucified body is not of a criminal, but is of the same Son of God, then ''the land'' is not defiled, but purified by his magic blood.
But there is a logical problem: if the blood of the Son is a blood who purifies, then why must not that body continue to be hung on the tree ? Jesus should not to be buried the same day, in order that the land is really purified by his body being hung on the tree during all the night.
To bury Jesus before the night means to consider his body the body of a criminal, of a sinner.
If ''Mark'' had this goal in mind, by inventing the burial of Jesus during the same day of the his death, then ''Mark'' cannot have satisfied the other requisite: the purification of the land.
Viceversa, if Marcion wrote the first Gospel, then the midrash from Deut 21:23 makes really sense for his theology: Jesus is considered a sinner. --> He is buried before the night. ---> He did not purify the land with the his magic blood.---> the sins of Israel remain all on the people (and with them the rule of the Demiurge on Israel).
There is not expiatory death in Marcionite thelogy.
Under that hypothesis, then that scripture gives a clue of the ''where'' of the crucifixion:
You must not defile the land that the Lord your God is giving you for possession.
