Deuteronomy 19:4

And this is the case of the manslayer, that shall flee thither and live: whoso killeth his neighbor unawares, and hated him not in time past;

“Here is the law concerning a case of someone who kills a person and flees there to save his life, having killed his neighbor accidentally without previously hating him:

“This is the provision for the manslayer, who by fleeing there may save his life. If anyone kills his neighbor unintentionally without having hated him in the past—

And this is the case of the slayer, which shall flee thither, that he may live: Whoso killeth his neighbour ignorantly, whom he hated not in time past;

“Now this is the case of the one who commits manslaughter, who may flee there and live: when he kills his friend unintentionally, not hating him previously—

This is the rule concerning anyone who kills a person and flees there for safety—anyone who kills a neighbor unintentionally, without malice aforethought.

“And this is the case of the manslayer who flees there, that he may live: Whoever kills his neighbor unintentionally, not having hated him in time past—

“If someone kills another person unintentionally, without previous hostility, the slayer may flee to any of these cities to live in safety.
