Purity of arms (Hebrew: טוהר הנשק, romanized: Tohar HaNeshek) is one of the core values listed in the "Spirit of the Israel Defense Forces". It is described as the following:
The IDF servicemen and women will use their weapons and force only for the purpose of their mission, only to the necessary extent and will maintain their humanity even during combat. IDF soldiers will not use their weapons and force to harm human beings who are not combatants or prisoners of war, and will do all in their power to avoid causing harm to their lives, bodies, dignity and property. The assertion of this ethical code by Israel has historically spurred controversy over the course of the Arab–Israeli conflict. Many Israeli war crimes have been documented, including the use of torture, killing of civilians and prisoners of war, indiscriminate attacks, collective punishment and starvation, as well as the Gaza genocide.
