Numbers 35:22-24

MSTC(i) 22 But and if he pushed him by chance and not of hate, or cast at him with any manner of thing and not of laying of wait, 23 or cast any manner of stone at him that he die therewith, and saw him not, and he cast it upon him and he died, but was not his enemy, neither sought him any harm; 24 then the congregation shall judge between the slayer and the executer of blood in such cases.
