Judge Yaakov Bazak, whose office displayed a portrait of Zvi Yehuda Kook, sympathized with the despair of Hebron settlers at government inaction to clamp down on terrorism, and said that the target of the terror, the Islamic College, taught, "with great fanaticism, hatred of Jews". During a trial recess, as a result of a successful negotiation to exchange prisoners, finalized in the Jibril Agreement, among the 1,100 Arab prisoners released were the killers convicted of the Beit Hadassah murders, and the murderer of Aharon Gross. This affected the sentencing: Major Rehavam Ze'evi placed blame on the government, and stated that despair had led the terrorists, "pioneers, men of vision and faith", to take the law into their own hands. Ben-Zion was released in 1989. Shaul Nir, Menachem Livni, and Uzi Sharbaf received life sentences (24 years), while the others received terms of imprisonment ranging from 3 to 9 years. 20 members were released after less than 2 years, in September 1986. The three life sentences were controversially commuted three times by then-President Chaim Herzog, finally to 10 years, and with time off for good behavior, they were released on December 27, 1990, and hailed as "heroes" by leaders of the Gush Emunim movement. Major Rehavam Ze'evi was killed by a Palestinian terrorist in 2001, while Shaul Nir was shot and critically wounded in a drive-by attack on 9 December 2015.
