Numbers 15:2-3

“Give the following instructions to the people of Israel. “When you finally settle in the land I am giving you, you will offer special gifts as a pleasing aroma to the LORD. These gifts may take the form of a burnt offering, a sacrifice to fulfill a vow, a voluntary offering, or an offering at any of your annual festivals, and they may be taken from your herds of cattle or your flocks of sheep and goats.
