Numbers 15:1-4

Then the LORD told Moses, “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. When you present these offerings, you must also give the LORD a grain offering of two quarts of choice flour mixed with one quart of olive oil.
