But woe unto you, Pharisees: for ye tithe mint and rue and all manner of herbs, and pass over judgment and the love of God: these ought ye to have done, and not to leave the other undone. Probably the primitive Law of Moses, which directed that a tenth of every income in Israel should be given up to the service of the invisible King alone, referred to such important products as corn, and wine, and oil, and the like; but the present elaboration of the Law and the Pharisee schools had extended the primitive obligation to the smallest garden herbs, such as mint and rue.
The Talmud even condescends to discuss whether, in tithing the seeds of these garden herbs, the very stalk too ought not to be tithed! The Master, ever tender and considerate, does not blame this exaggerated scrupulosity, if it were done to satisfy even a warped and distorted conscience; what he does find fault with, though, and in the bitterest terms language can formulate, is the substitution of and the clear preference for these infinitely lower duties for the higher.
