Obvious Corruption of Scripture in the Book of John.

John 18:28. Then they led Y’shua from Caiaphas to the praetorium: it was early: but they did not enter the praetorium, so that they would not be defiled, but could eat the Seder.

This brief reference had to be added by someone who did not know Jewish customs or that the Seder had been eaten the previous evening as recorded in Matthew, Mark, and Luke. John does not call the meal a Seder, but the meal in John 13 was a Seder, attested by the quote below. The Seder was eaten at home and did not require sanctification in order to eat the Seder, the Passover meal.
