Rabbi Bar-Hayim was born David Mandel 24 February 1960 in Sydney, Australia.
He studied at the Merkaz Harav Kook yeshiva in Jerusalem for 10 years.
He now lectures in the greater Jerusalem area and publishes articles in English and Hebrew on various web sites. that the Ashkenazi Jewish practice which had evolved in Europe until that time should be enshrined, denying the possibility of any change whatever, even where such change is mandated by the Torah itself."
He has proposed the re-establishment of Minhagei, religious customs and practices that reflect those of the pre-exile Jewish communities in Israel, rather than those of Babylon or Europe. Foreign this purpose, he has published a prayer book intended to reflect the ancient nusach tefillah of ancient Israel, "Nusach ", based upon the Jerusalem Talmud, for use at his Machon Shilo, a beth din and an institute of Jewish learning in Jerusalem dedicated to Torat
He has argued for the return of the primacy of the Jerusalem Talmud and gives more weight to rulings contained therein. He has proposed that when the first day of Sukkot falls on Shabbat, Israeli Jews should follow the Mishna and Talmud Yerushalmi"s ruling and perform the lulav ritual.
He states that one should say Hallel on Israeli Independence Day.
