Lehava ( LeMeniat Hitbolelut B'eretz HaKodesh; "Prevention of Assimilation in the Holy Land") is a Jewish far-right organization based in Israel that strictly opposes Jewish assimilation, objecting to any personal or business relationships between Jews and non-Jews. It is opposed to the Christian presence in Israel. 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".
In January 2015 Channel 2 reported that Defense Minister Moshe Ya'alon may be preparing to categorize Lehava as a terrorist organization. Ya'alon was reported to have ordered the Shin Bet and the Defense Ministry to assemble evidence required for the classification. Three members of Lehava were arrested and indicted in 2014 for committing arson and spray-painting anti-Arab graffiti at the Max Rayne Hand in Hand: Center for Jewish Arab Education in Israel (Yad B'Yad) Bilingual School in Jerusalem, and Lehava's leader, Ben Zion Gopstein, along with other group members were arrested shortly thereafter for incitement. The arson incident received international attention. Reuters reports that government action against Lehava has only come following months of petitioning by "left-leaning Israelis and media commentators". In response, Gopstein issued a statement harshly critical of Ya'alon: "I suggest that [Ya'alon] aim to outlaw the Islamist Movement and then preoccupy itself with an anti-assimilation group.... Instead of taking care of an enemy of Israel, the defense minister is trying to win over votes from the Left [by] taking on Lehava. The group acts to save the daughters of Israel [Jewish women] and deserves the Israel Prize."
