Mark 5:18-20

Amplified Bible

¹⁸ As He was stepping into the boat, the [Gentile] man who had been demon-possessed was begging with Him [asking] that he might go with Him [as a disciple]. ¹⁹ Jesus did not let him [come], but [instead] He said to him, “Go home to your family and tell them all the great things that the Lord has done for you, and how He has had mercy on you.” ²⁰ So he [obeyed and] went away and began to publicly proclaim in Decapolis [the region of the ten Hellenistic cities] all the great things that Jesus had done for him; and all the people were astonished.
