Deuteronomy 18:3-5

Tree of Life Version

³ So this will be the share due to the kohanim from the people—from those who offer a sacrifice, whether a bull or sheep, they are to give the kohen the shoulder, two cheeks, and the stomach. ⁴ The firstfruits of your grain, of your new wine, of your oil, and the first fleece of your sheep, you are to give him. ⁵ For Adonai your God has chosen him from all your tribes to stand and serve in the Name of Adonai—him and his sons forever.
