Num 35:9-11

Selection and Appointment of Cities of Refuge for Unpremeditated Manslayers. - Num 35:10, Num 35:11. When the Israelites had come into the land of Canaan, they were to choose towns conveniently situated as cities of refuge, to which the manslayer, who had slain a person (nephesh) by accident (בּשׁגגה: see at Lev 4:2), might flee. הקרה, from קרה, to hit, occurrit, as well as accidit; signifies here to give or make, i.e., to choose something suitable (Dietrich), but not “to build or complete” (Knobel), in the sense of קרה, as the only meaning which this word has is contignare, to join with beams or rafters; and this is obviously unsuitable here. Through these directions, which are repeated and still further expanded in Deu 19:1-13, God fulfilled the promise which He gave in Exo 21:13 : that He would appoint a place for the man who should unintentionally slay his neighbour, to which he might flee from the avenger of blood.
