Simon bar Kokhba
This Gemara contains also a remarkable saying of R. Abbahu, which is evidently directed against Christianity: "If a man says, 'I am God,' he lies; and if he says, 'I am the son of man,' he will have to repent; and if he says, 'I shall go up to heaven,' he will not do it, nor achieve what he promises" (2:1, 9a or 65b). It likewise relates how Simon bar Kokhba killed Eleazar of Modi'im, whom a Samaritan had falsely accused of treason.
