That the slayer that killeth [any] person unawares, [and] unwittingly, may flee thither,.... Who through mere accident, and without design, killed a person, friend or foe, one of his own kindred, or a stranger, without any malice against him, or intention to take away his life:
and they shall be your refuge from the avenger of blood; from any of the relations of the deceased, who might be stirred up to avenge the blood of his kinsman on the slayer; see Numbers 35:12.
