Numbers 35:30-32

Amplified Bible, Classic Edition

³⁰ Whoever kills any person [intentionally], the murderer shall be put to death on the testimony of witnesses; but no one shall be put to death on the testimony of one witness.

³¹ Moreover, you shall take no ransom for the life of a murderer guilty of death; but he shall surely be put to death.

³² And you shall accept no ransom for him who has fled to his city of refuge, so that he may return to dwell in the land before the death of the high priest.
