“And when they had set them in the middest, they asked, By what power, or by what name haue ye done this?”
1611 King James Version (KJV)
4:7 By what name - By what authority, have ye done this? - They seem to speak ambiguously on purpose.
Ac 4:7 Set them in the midst. The high priest acted as president, and the members were arranged in a semi-circle around him, with the prisoners in front. By what power, or by what name? They could not deny the miracle, but they thought that it had been done by some incantation. They ask an explanation.
