Numbers 35:22-24

Amplified Bible

²² ‘But if he pushed the victim suddenly, not in enmity, or threw anything at him without malicious intent, ²³ or without seeing him hit him [accidentally] with a stone object that could kill him, and he died, and [the offender] was not his enemy nor intending to harm him, ²⁴ then the congregation shall judge between the offender and the blood avenger according to these ordinances.
