Numbers 15:17-22

¹⁷And the Lord spake with Mosheh, saying:

¹⁸Speak with the sons of Israel, and say to them, When you have come into the land into which I will bring you,

¹⁹and when you eat of the bread of the land, you shall set apart a separation before the Lord.

²⁰Of the first of your food you shall set apart a cake for a separation; as the separation of the threshing-floor, so shall you set it apart;

²¹Of the first of your bread (dough) you shall give the separation before the Lord in your generations.

²²And should you be in ignorance, and not do all these commandments of which the Lord hath spoken with Mosheh,
