Mark 5:11 WEB

⁹  He asked him, 'What is your name?' He said to him, 'My name is Legion, for we are many.'

¹⁰  He begged him much that he would not send them away out of the country.

¹¹  Now there was on the mountainside a great herd of pigs feeding.

¹²  All the demons begged him, saying, 'Send us into the pigs, that we may enter into them.'

¹³  At once Jesus gave them permission. The unclean spirits came out and entered into the pigs. The herd of about two thousand rushed down the steep bank into the sea, and they were drowned in the sea.
