Bible Reading Numbers 15:17-21

The Lord said to Moses, "Speak to the Israelites and tell them: When you enter the land into which I will bring you and begin to eat of the food of this land, you shall offer the Lord a contribution consisting of a cake of your first batch of dough. You shall offer it just as you offer a contribution from the threshing floor. Throughout your generations you shall give a contribution to the Lord from your first batch of dough."
