Parallel
Deuteronomy 19:5
World English Bible British Edition · Berean Standard Bible
as when a man goes into the forest with his neighbour to chop wood and his hand swings the axe to cut down the tree, and the head slips from the handle and hits his neighbour so that he dies—he shall flee to one of these cities and live.
If he goes into the forest with his neighbor to cut timber and swings his axe to chop down a tree, but the blade flies off the handle and strikes and kills his neighbor, he may flee to one of these cities to save his life.
