Numbers 35:22-24

Young's Literal Translation

²² `And if, in an instant, without enmity, he hath thrust him through, or hath cast at him any instrument, without lying in wait;

²³ or with any stone wherewith he dieth, without seeing, and causeth [it] to fall upon him, and he dieth, and he [is] not his enemy, nor seeking his evil;

²⁴ then have the company judged between the smiter and the redeemer of blood, by these judgments.
