Mark 5:13

13 So Jesus gave them permission. The evil spirits came out of the man and entered the pigs, and the entire herd of about 2,000 pigs plunged down the steep hillside into the lake and drowned in the water.

Mark 5:13 In-Context

11 There happened to be a large herd of pigs feeding on the hillside nearby.
12 “Send us into those pigs,” the spirits begged. “Let us enter them.”
13 So Jesus gave them permission. The evil spirits came out of the man and entered the pigs, and the entire herd of about 2,000 pigs plunged down the steep hillside into the lake and drowned in the water.
14 The herdsmen fled to the nearby town and the surrounding countryside, spreading the news as they ran. People rushed out to see what had happened.
15 A crowd soon gathered around Jesus, and they saw the man who had been possessed by the legion of demons. He was sitting there fully clothed and perfectly sane, and they were all afraid.
