Luke 8:30-32

New Living Translation

³⁰ Jesus demanded, “What is your name?”

“Legion,” he replied, for he was filled with many demons. ³¹ The demons kept begging Jesus not to send them into the bottomless pit.^[a]

³² There happened to be a large herd of pigs feeding on the hillside nearby, and the demons begged him to let them enter into the pigs.

So Jesus gave them permission.
