“But Peter said unto him, Thy money perish with thee, because thou hast thought that the gift of God may be purchased with money.”
King James Version (KJV)
Ac 8:20 Peter said. Peter's outburst of indignation is characteristic. Thy money perish with thee. Not an anathema, but the statement of a fact, unless he repents. Because thou hast thought. Observe that, in Peter's rebukes, the thought is, not that he has never been converted, but that he has now committed an awful sin. It is "one sin", not his "sins", that stands out in every sentence.
