Final answer:
John 4:23 does not discuss the presence of Galileans at a feast in Jerusalem, but Galileans likely witnessed Jesus's miracles during major Jewish feasts as they were common pilgrims in Jerusalem at such times, according to other parts of the Gospels.
Step-by-step explanation:
The student's question seems to be misquoting the verse or referencing an interpretation not found in the standard biblical text. John 4:23 actually discusses worship in truth and spirit, not the activities of Galileans at a feast. There is no direct biblical account in John 4:23 that explains why the Galileans had seen all that Jesus did in Jerusalem at the feast. Instead, other parts of the Gospels, such as John 2:23, suggest that many people, including Galileans, believed in Jesus because of the miracles He performed during the Passover feast in Jerusalem.
During biblical times, Jerusalem was a central location for Jewish pilgrimage, especially during major feasts such as Passover when Jesus's actions would have been more public and witnessed by many, including Galileans. It was common for Jews from various regions, including Galilee, to attend these large gatherings, which is likely why Galileans were present and able to witness Jesus's deeds.
