How many of Jesus chosen disciples were at the Sermon on the Mount ?

There were twelve disciples chosen by Jesus, as recorded in Matthew 10:2-4. Three of these disciples were present at the Sermon on the Mount: Peter, James, and John. This can be inferred from Matthew 5:1, which states, "Now when he saw the crowds, he went up on a mountainside and sat down. His disciples came to him." The disciples mentioned here likely include Peter, James, and John, as they were among Jesus' closest followers and often accompanied him to significant events, such as the Transfiguration (Matthew 17:1-2).

While all twelve disciples were chosen by Jesus, it is important to note that not all of them were necessarily present at every event or teaching moment. In this case, it appears that only three of the chosen disciples were at the Sermon on the Mount. This highlights the significance of Peter, James, and John among Jesus' inner circle of disciples.
