Numbers [In the desert] 18:27-28

²⁷Your wave offering shall be credited to you, as though it were the grain of the threshing floor, and as the fullness of the wine press.

²⁸Thus you also shall offer a wave offering to Adonai of all your tithes, which you receive of the children of Israel God prevails; and of it you shall give Adonai ’s wave offering to Aaron Light-bringer the priest.
