“Rue ” means
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.
