17. Then the Lord spoke to Moses, saying,
18. "Speak to the sons of Israel and say to them, 'When you enter the land where I bring you,
19. then it shall be, that when you eat of the food of the land, you shall lift up an offering to the Lord.
20. Of the first of your dough you shall lift up a cake as an offering; as the offering of the threshing floor, so you shall lift it up.
21. From the first of your dough you shall give to the Lord an offering throughout your generations.
