New Defender's Study Bible Notes
15:4 shall he that offereth. The reason why a number of new legal regulations are inserted here between the historical narratives of Numbers 14 and 16 can only be that this was the point in time when Moses received them from the Lord. This is an incidental confirmation of the Mosaic authorship of Numbers. Any later “redactor” would surely have included them with the other regulations on the offerings in Leviticus.
