Deuteronomy 22:9

Together. If wheat was sown in a vineyard, it would ripen much sooner than the grapes; and as the first-fruits of both were offered to the Lord, the owner would lose the profit which he had too greedily sought after, the place being esteemed both pure and impure at the same time. This mixture of seeds would also impoverish the land, so that it would be like a place defiled, and unfit for cultivation. (Jansenius in Leviticus xix. 19.) Maimonides supposes that the practice of the Zabians is here reprobated. They sowed the land with corn and dry grapes, in honour of Ceres and Bacchus, (More. Nev. p. 3. c. 37,) who presided over the harvest and vintage among the pagans. (Wm. of Paris. Leg. 13.) --- Moses might also, by this symbolical language, condemn unnatural connexions, as he perhaps does, ver. 10.
