Deuteronomy 22:9. Thou shalt not sow thy vineyard with divers seeds: lest the fruit of thy seed which thou halt sown, and the fruit of thy vineyard, be defiled.
The Zabians were accustomed to sow barley and dried grapes together, believing that without this union there would not be a good vintage; but that with it the gods would be propitious to them. Bishop Patrick observes, that if the Israelites had done this the fruits of the harvest would have been impure, because associated with idolatry. The firstfruits would not have been accepted by God, and hence the whole crop would have been useless.
