Tares
Tares. The tares are also enemies of the grain. In his Parable of the Tares, JESUS said: "While men slept, his enemy came and sowed tares among the wheat" (Matthew 13:25). In the Holy Land, tares are something called "wild wheat," because they resemble wheat, only the grains are black. Thomson has this to say about the tares:
"The Arabic name for tares is zawan, and they abound all over the East, and are a great nuisance to the farmer. The grain is small, and is arranged along the upper part of the stalk, which stands perfectly erect. Its taste is bitter, and when eaten separately, or when diffused in ordinary bread, it causes dizziness, and often acts as an emetic. In short, it is a strong soporific poison, and must be carefully winnowed, and picked out of the wheat, grain by grain, before grinding, or the flour is not healthy. Of course the farmers are very anxious to exterminate it, but that is nearly impossible. [Manners And Customs of Bible Lands]
