New King James Version

²⁸ because he should have remained in his city of refuge until the death of the high priest. But after the death of the high priest the manslayer may return to the land of his possession.

²⁹ ‘And these things shall be ^(A)a statute of judgment to you throughout your generations in all your dwellings. ³⁰ Whoever kills a person, the murderer shall be put to death on the ^(B)testimony of witnesses; but one witness is not sufficient testimony against a person for the death penalty.
