Ezekiel 44:30

And the first of all the first-fruits of all things, which had to be dedicated to the Lord, Exodus 23:19; Exodus 34:26; Numbers 18:13; Deuteronomy 28:4, and every oblation of all, gifts offered to the Lord by heaving and waving, of every sort of your oblations, shall be the priest's, as part of his emoluments; ye shall also give unto the priests the first of your dough, of the grain-corn, that he may cause the blessing to rest in thine house, for the blessing of God rests upon him who, in simple faith, performs the duties laid upon him.
