Philo: On Dreams

XI. (2.75) It is on this account that Moses set apart an especial festival for the sheaf; however, not for every sheaf, but for that which came from the sacred land. "For when," says he, "you come into the land which I give unto you, and when you reap its harvest, you shall bring sheaves as a first fruit of your harvest to the Priest."

(2.76) And the meaning of this injunction is, when, O mind, you come into the country of virtue, which it is fitting should be offered up to God

alone, being a land good for pasture, a land of rich soil, a land which beareth fruit, and when you reap the fruit (either that afforded by the land spontaneously or that which thou hast sown), which has been brought to perfection by the God who gives perfection; carry it not home to thy house; that is to say, do not store it up, and do not attribute to thyself the cause of the crop which has arisen to thee, before thou has offered the first fruits to the Cause of all wealth, and to him who persuaded thee to study the operations which confer riches.

(2.77) And it is enjoined that you shall offer the "first fruits of your own harvest;" not of the harvest of the land, in order that we may reap and gather in the harvest for ourselves; dedicating to God all good and nutritious, and beneficial fruits.
