The writer continues giving background information about Stephen and other people that is important to understanding the story. (See: [[rc://en/ta/man/translate/writing-background]])
# there arose some people ... Asia. These people were debating with Stephen
The word "arose" is an idiom that represents beginning to act. These people did not begin to rise into the air, nor did they necessarily get up from a sitting position. Alternate translation: "some people ... Asia, began to debate against Stephen" (See: [[rc://en/ta/man/translate/idiom]])
Possible meanings are 1) the Cyrenians, the Alexandrians and those from Cilicia and Asia were all members of the synagogue of the Freedmen; 2) the Cyrenians and the Alexandrians were members of the synagogue of the Freedmen, but those from Cilicia and Asia were not; or 3) there were three separate groups of people: those from the synagogue, those from Cyrene and Alexandria, and those from Cilicia and Asia.
"Freedmen" were probably ex-slaves from these different locations. It is unclear if the other people listed were part of the synagogue or just participated in the debate with Stephen.
