Numbers 15:2-4

New Revised Standard Version, Anglicised Catholic Edition

² Speak to the Israelites and say to them: When you come into the land you are to inhabit, which I am giving you, ³ and you make an offering by fire to the Lord from the herd or from the flock—whether a burnt-offering or a sacrifice, to fulfil a vow or as a freewill-offering or at your appointed festivals—to make a pleasing odour for the Lord, ⁴ then whoever presents such an offering to the Lord shall present also a grain-offering, one-tenth of an ephah of choice flour, mixed with one-fourth of a hin of oil.
