Hesder
Hesder (in Hebrew: "arrangement"; also Yeshivat Hesder ישיבת הסדר) is an Israeli yeshiva program which combines advanced Talmudic studies with military service in the Israel Defense Forces, usually within a Religious Zionist framework. These yeshivot allow religious Jews to fulfill the ideal of full and active participation in the defense of the Israeli people, while still engaging in Torah study during their formative years.
