NET Bible
"He must remain in that city until his case is decided by the assembly and the high priest dies. Then the one who committed manslaughter may return home to the city from which he escaped.”"
— Joshua 20:6, NET Bible
“And he shall dwell in that city, until he stand before the congregation for judgment, and until the death of the high priest that shall be in those days: then shall the slayer return, and come unto his own city, and unto his own house, unto the city from whence he fled.”
“And he shall dwell in that city, until he stand before the congregation for judgment, until the death of the high priest that shall be in those days: then shall the manslayer return, and come unto his own city, and unto his own house, unto the city from whence he fled. ”
“He shall dwell in that city until he stands before the congregation for judgment, until the death of the high priest that shall be in those days. Then the manslayer shall return, and come to his own city, and to his own house, to the city he fled from.'"”
“And he shall dwell in that city, till he stand before judgment to give an account of his fact, and till the death of the high priest, who shall be at that time: then shall the manslayer return, and go into his own city and house from whence he fled.”
“And he is to go on living in that town till he has to come before the meeting of the people to be judged; (till the death of him who is high priest at that time:) then the taker of life may come back to his town and to his house, to the town from which he had gone in flight.”
“And he shall dwell in that city, until he stand before the congregation for judgment, and until the death of the high priest that shall be in those days: then shall the slayer return, and come unto his own city, and unto his own house, unto the city from whence he fled.”
Anyone who accidentally kills someone can escape there; these cities will be a place of asylum from the avenger of blood.
The one who committed manslaughter should escape to one of these cities, stand at the entrance of the city gate, and present his case to the leaders of that city. They should then bring him into the city, give him a place to stay, and let him live there.
When the avenger of blood comes after him, they must not hand over to him the one who committed manslaughter, for he accidentally killed his fellow man without premeditation.
He must remain in that city until his case is decided by the assembly and the high priest dies. Then the one who committed manslaughter may return home to the city from which he escaped.”
So they selected Kedesh in Galilee in the hill country of Naphtali, Shechem in the hill country of Ephraim, and Kiriath Arba(that is, Hebron) in the hill country of Judah.
Beyond the Jordan east of Jericho they selected Bezer in the wilderness on the plain belonging to the tribe of Reuben, Ramoth in Gilead belonging to the tribe of Gad, and Golan in Bashan belonging to the tribe of Manasseh.
These were the cities of refuge appointed for all the Israelites and for resident foreigners living among them. Anyone who accidentally killed someone could escape there and not be executed by the avenger of blood, at least until his case was reviewed by the assembly.
