'Great Things' in the Bible

Jerusalem, Idumaea, the east side of the Jordan River, and from around Tyre and Sidon [i.e., cities on the northwest coast of Palestine] came to Him, having heard about the great things [i.e., miracles] He had been performing.

But Jesus would not allow him, saying to the man, "Go home to your friends [and family?] and tell them about the great things the Lord has done for you and how He had pity on you."

But the man went away and began telling people throughout Decapolis about all of the great things Jesus had done for him. [Note: "Decapolis" means "ten cities" and was a region located east of the Jordan River].

For the Mighty One has done great things for me, and His name is holy.

"Return to your house and tell people about the great things God has done for you." So, he went on his way, proclaiming throughout the whole town [i.e., Gerasa. See verse 26] the great things Jesus had done for him.
