Leviticus 23:17-18

Ye shall bring out of your habitations two wave-loaves of two tenth parts of an ephah: they shall be of fine flour, they shall be baken with leaven, for first-fruits unto Jehovah. And ye shall present with the bread seven lambs without blemish a year old, and one young bullock, and two rams: they shall be a burnt-offering unto Jehovah, with their meal-offering, and their drink-offerings, even an offering made by fire, of a sweet savor unto Jehovah.
