Numbers 15:1,2 - Joseph Benson’s Commentary on the Old and New Testaments

When the following laws were delivered, is uncertain. But it would seem, from Numbers 15:23, to have been toward the end of their peregrinations, and not long before their settlement in Canaan, consequently at a time when part of that mutinous generation, mentioned in the former chapter, were cut off by death. If this remark be just, these laws were enjoined only to the children of the murmurers, who had not forfeited a right to the inheritance in the promised land, as their fathers had done. Le Clerc, however, is of opinion that the laws here recorded were delivered before the rebellion recorded in the former chapter.
