Numbers 35:31-32

35:31 Moreover, you must not accept a ransom for the life of a murderer who is guilty of death; he must surely be put to death. 35:32 And you must not accept a ransom for anyone who has fled to a town of refuge, to allow him to return home and live on his own land before the death of the high priest. ¹ 

[35:32]  ¹ tn Heb “the priest.” The Greek and the Syriac have “high priest.” The present translation, along with many English versions, uses “high priest” as a clarification.
