Numbers 15:17-21 - Rules For First Fruits
17 And Jehovah will speak to Moses, saying, 18 Speak to the sons of Israel, and say to them, In your going into the land where I bring you there, 19 And it was in your eating from the bread of the land, ye shall lift up a lifting up to Jehovah. 20 The first of your groats, a cake, shall ye lift up a lifting up; as the lifting up of the threshing floor, so shall ye lift it up. 21 From the first of your groats, shall ye give to Jehovah a lifting up, for your generations.
