"The fact that the entire large herd of pigs—two thousand, according to Mark—rushed down the bank and drowned in the lake shows that Jesus indeed cast a huge host of demons out of the afflicted man. (They called themselves “Legion, for we are many” (Mark 5:9); a Roman legion had several thousand
soldiers.)
Presumably if there had only been one demon, or just a few, only that many pigs would have rushed away. But when thousands of pigs were affected, this was evidence of a very powerful exorcism, showing that the kingdom of God had indeed come with great power in the person and ministry of Jesus.
Jesus realized that such a demonstration would be worth making to everyone in the area, including the swineherd, even if it cost the swineherd his entire livelihood.
Jesus told the parables of the hidden treasure and the pearl of great value to illustrate how finding the kingdom of God is worth giving up everything we have.”
