Rue occurs only in Luke 11:42. The rue here spoken of is doubtless the common Ruta graveolens, a shrubby plant about two feet high, of strong medicinal virtues. It is a native of the Mediterranean coasts, and has been found by Hasselquist on Mount Tabor. The Talmud enumerates rue amongst kitchen-herbs, and regards it as free of tithe, as being a plant not cultivated in gardens. In our Lord’s time, however, rue was doubtless a garden plant, and therefore tithable.
