Final answer:
In the New Testament Gospels, it is the disciples who ask Jesus about the signs of the end of times. Various passages recount how they sought Jesus' teachings on matters of great importance, including prophetic events.
Step-by-step explanation:
The question about who asks Jesus about signs for the end of times refers to an event described in the Christian New Testament. In the Gospels, particularly in Matthew 24, Mark 13, and Luke 21, it is indicated that the disciples approach Jesus to inquire about the signs of the end of the age. The question they pose is, "Tell us, when will these things be, and what will be the sign of Your coming, and of the end of the age?" Transactions such as the betrayal of Jesus by one of the apostles, the resurrection of Jesus, and the tax collector episode showcase interactions between Jesus and his disciples on several pivotal matters. In the context of Leonardo's depiction, where apostles react to the news of betrayal, it is an example of how the apostles frequently sought understanding and clarification from Jesus on various issues.
