Great(i) 22 But and yf he pusshed hym by chaunce and not of hate, or cast at him with any maner of thynge and not of layinge of wayte: 23 or cast any maner of stone at him (that a man maye dye with) and sawe hym not. And he cast it vpon hym and he dye, and was not hys enemye, nether sought him any harme. 24 Then the congregacyon shall iudge betwene the slayer and the executer of bloude in soche cases.
