Commentary on Numbers 35:20

• John Gill (Reformed Baptist), Exposition of the Old and New Testaments on Numbers 35:20: But if he thrust him of hatred,.... Or, "and if" (r), since the Scripture is still speaking of such that shall die for murder, though in another instance, without having the privilege of a city of refuge; if he thrusts him with a sword or knife, or rather, since, if anything of that kind is included in the first instance of smiting with an instrument...
• Keil & Delitzsch (Lutheran), Biblical Commentary on the Old Testament on Numbers 35:20-23: Num 35:20-23 And so also the man who hit another in hatred, or threw at him by lying in wait, or struck him with the hand in enmity, so that he died. And if a murderer of this kind fled into a free city, the elders of his city were to have him fetched out and delivered up to the avenger of blood (Deu 19:11-12).
