Numbers 15:17-21 - Rules For First Fruits

17 And Jehovah spoke to Moses, saying, 18 Speak unto the children of Israel, and say unto them, When ye come into the land whither I bring you, 19 then it shall be, when ye eat of the bread of the land, that ye shall offer a heave-offering to Jehovah; 20 the first of your dough shall ye offer, a cake, for a heave-offering; as the heave-offering of the threshing-floor, so shall ye offer this. 21 Of the first of your dough ye shall give to Jehovah a heave-offering throughout your generations.
