John Gill Commentary Numbers 29:36

"but ye shall offer a burnt-offering, an offering made by fire, of a sweet savor unto Jehovah: one bullock, one ram, seven he-lambs a year old without blemish;" — Numbers 29:36 (ASV)

Ver. 36-38. But you shall offer a burnt offering

Which was the same that was offered on the first and tenth days of this month, (Numbers 29:2Numbers 29:8) and the meat and drink offerings for each of the creatures were the same, as often expressed; and on this day a goat for a sin offering was also offered, besides the daily sacrifice, and what went along with that.
