Rashi on Numbers 28:4/רש"י על במדבר כ״ח:ד׳

1את הכבש אחד THE ONE LAMB [SHALT THOU OFFER IN THE MORNING] — Although it has already been stated in the section beginning with the words ,ואתה תצוה (Exodus 29:38 39): “Now this is what thou shalt offer … [The one lamb thou shalt offer in the morning]”, that was an instruction for the days of the installation ceremony of the priests, but here it states the commands for all generations.
