This book about the Messianic Old Testament prophesies in the Light of Rabbinical Writings has already seen five Hebrew editions in Israel. It is the first study written in modern Hebrew by a gentile scholar. According to the writer he is making a kind of “Nahson’s leap”, the first one to jump into the Red Sea at Moses’ command. The item is somewhat delicate. The writer is stepping into the lion’s den of the Rabbis and into the fiery furnace of the liberal theologians. But he hopes that others will follow him and promote a similar dialogue in the spirit of tolerance and spiritual democracy.
