Albert Barnes Commentary Numbers 28:1

"And Jehovah spake unto Moses, saying," — Numbers 28:1 (ASV)

The daily offering had already been commanded (Exodus 29:38), and no doubt additional offerings had become customary on festivals. But no such elaborate system as is here prescribed was or could possibly have been observed in the wilderness: compare Deuteronomy 12:8-9. The regulations of this and the next chapter therefore point to the immediate prospect of that settlement in Canaan which alone could enable the Israelites to obey them. Compare the ordinances in Numbers 15:0.
