דבר אל אהרן ואל בניו כי הם השוחטים במדבר. דבר אל אהרן ובניו, “speak to Aaron and his sons;” they were the slaughterers during all the years that the Israelites were in the desert.
ואל כל בני ישראל על ידי שפרשה זו מזהרת בשחיטת קדשים סמוכה כאן. ואל כל בני ישראל, “and to all the Children of Israel.” The reason why this paragraph is inserted here is that it deals with the procedures for slaughtering animals that are to serve as sacrificial animals. As long as the Israelites were in the desert and they all dwelled around the Tabernacle, it was no hardship for them to eat meat only after the animals had first been sanctified as sacrifices, and as a byproduct of getting used to this they were weaned from the practice of offering animal sacrifices to satyrs, as they had been doing in Egypt.
