What does Luke 8:35 mean?
Pig herders have just watched about two thousand pigs (Mark 5:13) spontaneously charge down a hill and rush into the Sea of Galilee where they drown (Luke 8:33). Astonished—and probably afraid that they will have to pay for the pigs—the herders spread the word in the nearby city and the surrounding countryside (Luke 8:34). According to Matthew, the herdsmen "told everything, especially what had happened to the demon-possessed men" (Matthew 8:33). The entire city as well as the district come out to see the spectacle (Matthew 8:34; Luke 8:37). When they arrive, they find that the local madman is completely restored.The people know this man very well. They had repeatedly bound his hands and feet and kept him under guard, possibly in the city (Luke 8:29). They've also seen him break the ropes fastened to his feet, as well as the handcuffs on his wrists, and flee to the tombs (Luke 8:27). There, he tends to strip off his clothing, cry out, and gash his flesh with stones (Mark 5:5). The sudden transformation terrifies them.
The disciples don't necessarily know the man's history, but they have seen additional changes. When they arrived, the man had charged Jesus, crying out, "What have you to do with me, Jesus, Son of the Most High God? I beg you, do not torment me" (Luke 8:28; cf. Mark 5:6–7). Now, the man calmly sits at Jesus' feet, so at peace that he begs Jesus to take him along (Luke 8:38).
The Gospels describe several people as sitting at Jesus' feet—the position of a student before his rabbi—including a sinful woman (Luke 7:38), a woman who chooses to learn rather than engage in the customs of hospitality (Luke 10:39), and a Samaritan (Luke 17:16). In that era, this was an unthinkably unusual group for a Jewish rabbi.
