Final answer:
Pilate remembers the Passover tradition of releasing one prisoner during the Jewish festival. Passover celebrates the Israelites' Exodus from Egypt, which involved miraculous events including the sparing of Jewish homes by the Angel of Death.
Step-by-step explanation:
When the public flogging is unsuccessful, Pilate remembers the Passover tradition of releasing one prisoner, which was customary during the Jewish festival. During Passover, Jews commemorate the Exodus from Egypt when Moses led the Israelites out of slavery. The Bible recounts a series of plagues sent by God to persuade Pharaoh to release the Jews, culminating in the death of the firstborn Egyptian sons. Jewish homes marked with lamb's blood were spared by the Angel of Death in an event known as the 'Passover'. This miraculous salvation is celebrated annually by Jews with a seder, a ritual meal that begins the holiday, and the retelling of the Exodus story.
