Parallel
Deuteronomy 19:5
Brenton's English Septuagint · Berean Standard Bible
And whosoever shall enter with his neighbour into the thicket, to gather wood, if the hand of him that cuts wood with the axe should be violently shaken, and the axe head falling off from the handle should light on his neighbour, and he should die, 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.
