18“Speak to the Israelites and tell them: When you enter the land to which I am bringing you
19and you eat the food of the land, you shall lift up an offering to the LORD.
20From the first of your dough, you are to lift up a cake as a contribution; offer it just like an offering from the threshing floor.
21Throughout your generations, you are to give the LORD an offering from the first of your dough.
— Numbers 15:18-21
