'Man slayer' in the Bible

that the manslayer might flee there, who kills his neighbor unawares, and did not hate him in time past, and that fleeing to one of these cities he might live:

Thou shall prepare for thee the way, and divide the borders of thy land, which LORD thy God causes thee to inherit, into three parts, that every manslayer may flee there.

And this is the case of the manslayer, who shall flee there and live: Whoever kills his neighbor unawares, and did not hate him in time past,

Lest the avenger of blood pursue the manslayer, while his heart is hot, and overtake him, because the way is long, and smite him mortally, whereas he was not worthy of death, inasmuch as he did not hate him in time past.
