Numbers 9:11

11. The fourteenth day of the second month Thus a fundamental law is supplemented, and a standing ordinance is permanently established, in answer to prayer, first to Moses and then to the Lord. See chap. xxxvi for another instance. Bitter herbs of five kinds are eaten by the Jews as a salad with the paschal lamb; namely, lettuce, endive, chicory, and two others, the Hebrew names of which have not been identified with known plants. A very large number of bitter plants are eaten as salads in Syria, even the hearts of all the larger wild thistles. Says Tristram: “The leaves of the elecampane were gathered for salad by the Jehalin Arabs who accompanied us, as well as many cresses which grew in the southern desert, or at the south of the Dead Sea.”
