“And by the hands of the apostles were many signs and wonders wrought among the people; (and they were all with one accord in Solomon's porch.”
King James Version (KJV)
5:12 And they were all - All the believers.
Ac 5:12 By the hands of the apostles were many signs. Note that no one thus far has miraculous power but the apostles. The gift of miracles was not general. When it was imparted to others, we learn how it was imparted. See Ac 6:8 8:6,14. All with one accord in Solomon's porch. The apostles, in order to preach. See Ac 3:11. The brethren also with them.
