Numbers 15:17-21 - Rules For First Fruits

17 Yahweh spoke to Moses, saying, 18 "Speak to the children of Israel, and tell them, 'When you come into the land where I bring you, 19 then it shall be that when you eat of the bread of the land, you shall offer up a wave offering to Yahweh. 20 Of the first of your dough you shall offer up a cake for a wave offering: as the wave offering of the threshing floor, so you shall heave it. 21 Of the first of your dough you shall give to Yahweh a wave offering throughout your generations.
