25 “Then many of the Jews who had come to Mary, and had seen the things which Jesus did, believed on Him. But some of them went away to the Pharisees, and told them what things Jesus had done.” All of the Jews who had come to Mary did not believe, but many of them did. “But some of them,” whether of the Jews who had come, or of those who had believed, “went away to the Pharisees, and told them what things Jesus had done:” whether in the way of conveying intelligence, in order that they also might believe, or rather in the spirit of treachery, to arouse their anger. But whoever were the parties, and whatever their motive, intelligence of these events was carried to the Pharisees.
