Numbers 29:38-42

And one goat for a sin offering; beside the continual burnt offering, and his meat offering, and his drink offering.

These things ye shall do unto the LORD in your set feasts, beside your vows, and your freewill offerings, for your burnt offerings, and for your meat offerings, and for your drink offerings, and for your peace offerings.

And Moses told the children of Israel according to all that the LORD commanded Moses.
