Lehava (Hebrew: למניעת התבוללות בארץ הקודש‎‎ LeMeniat Hitbolelut B'eretz HaKodesh; "Prevention of Assimilation in the Holy Land") is a Jewish far-right^[1][2] organization based in Israel that strictly opposes Jewish assimilation, objecting to personal relationships between Jews and non-Jews.^[3][4][5] It is opposed to the Christian presence in Israel.^[6] It has an anti-miscegenation focus, denouncing marriages between Jewish women and non-Jewish, particularly Arab, men. Its actions have been denounced by President of Israel Reuven Rivlin as being like "rodents gnawing under the shared democratic and Jewish foundation of Israel".[2]
