John Lightfoot on Matthew 7:12

[Whatsoever ye would that men should do unto you, &c.] A certain Gentile came to Shammai, and said, 'Make me a proselyte, that I may learn the whole law, standing upon one foot': Shammai beat him with the staff that was in his hand. He went to Hillel, and he made him a proselyte, and said, That which is odious to thyself, do it not to thy neighbour: for this is the whole law.
