Yeshivat Har Hamor is a Religious Zionism yeshiva in Jerusalem, founded in 1997 as an offshoot of Yeshivat Merkaz Harav. The president of the yeshiva is Rabbi Tzvi Thau, and its other heads are Rabbis Amiel Sternberg and Mordechai Sternberg. There are currently around 450 students. Many are married ("avrechim"), and the average student age is higher than at most Religious Zionist yeshivas.
The name means "mountain of myrrh", based on Song of Songs 4:6, a phrase which in Jewish tradition refers to the Temple Mount. The word "HaMoR" is also an acronym for "Hemshech [=continuation of] Merkaz haRav".
The yeshiva was founded when a group of rabbis, led by Rabbi Tau, separated from Merkaz Harav. The broader cause of the separation was a disagreement between Rabbi Avraham Shapira, head of Merkaz Harav, and Rabbi Tau about the best approach for Torah education. The immediate cause was Rabbi Tau's opposition to the establishment of a teacher's college in the yeshiva - which in his opinion would damage the purity of the yeshiva's approach to Torah study. Much tension existed between the camps at the time, but it has declined with time. This was the first time a Religious Zionist yeshiva has split.
The yeshiva has been located at sites in several neighborhoods in western Jerusalem - Kiryat Menachem, then Bayit Vegan, and since 2008 in Kiryat Hayovel. There are future plans to move to the Har Homa neighborhood.
The yeshiva follows the teachings of Rabbi Abraham Isaac Kook and his son Rabbi Tzvi Yehuda Kook. It has a mamlachti ("statist") approach which sees special holiness in the institution of the State of Israel, which Rabbi Kook (the elder) termed "God's throne in the world". The yeshiva stands at the head of a number of institutions also connected to Rabbi Tau, which together are known as "yeshivot hakav" (yeshivas that follow the line).
In addition to the study of Talmud with the traditional commentators (Rishonim and Achronim), the yeshiva puts an emphasis on the study of Jewish thought ("machshava") according to the approach of Rabbi Kook.
Students typically serve in the Israeli army in a framework called "hesder Merkaz", as in Yeshivat Merkaz Harav.
