19And what the land is on which they dwell, whether it is good or bad; and what the cities are wherein these dwell, whether they dwell in walled cities or unwalled.
20And what the land is, whether rich or poor; whether there are trees in it or no: and ye shall persevere and take of the fruits of the land: and the days were the days of spring, the forerunners of the grape.
