Numbers 15:19-21

LEB(i) 19 whenever you eat from the food of the land, you will lift up a contribution to Yahweh. 20 You must lift up a contribution of the first batch of your ring-shaped dough bread; you must lift it up as a contribution of the threshing floor. 21 You will give to Yahweh a contribution from the first of your dough throughout your generations.*
