John Gill Commentary Numbers 29:2

"And ye shall offer a burnt-offering for a sweet savor unto Jehovah: one young bullock, one ram, seven he-lambs a year old without blemish;" — Numbers 29:2 (ASV)

And ye shall offer a burnt offering for a sweet savour unto the
Lord
Which was as follows:

one young bullock, one ram, and seven lambs of the first year without
blemish ,
which was the same, only one bullock less, with the offerings on the first day of the month, the seven days of unleavened bread, and the day of the firstfruits, (Numbers 28:11Numbers 28:19Numbers 28:27) .
