Deuteronomy 19

Deuteronomy 19:9

Three Cities more] Three other Cities of Refuge, over and above the six, here allowed, and conditionally enjoyned. Yet we never read more of them, that they were separated and set out. And that because the Jewes by their sins and breach of Covenant with God on their part, never got possession of the utmost Bounds of the Lands by God conditionally promised to them.
