(field culture). Patriarchal life was pastoral. After the conquest of Canaan, lands were meted and bounded, and landmarks held sacred (Deut. 19:1414Thou shalt not remove thy neighbor's landmark, which they of old time have set in thine inheritance, which thou shalt inherit in the land that the Lord thy God giveth thee to possess it. (Deuteronomy 19:14)). The valley soils of Palestine were fertile; natural waters abundant (Deut. 8:77For the Lord thy God bringeth thee into a good land, a land of brooks of water, of fountains and depths that spring out of valleys and hills; (Deuteronomy 8:7)); rain plentiful (Deut. 11:1414That I will give you the rain of your land in his due season, the first rain and the latter rain, that thou mayest gather in thy corn, and thy wine, and thine oil. (Deuteronomy 11:14); Jer. 5:2424Neither say they in their heart, Let us now fear the Lord our God, that giveth rain, both the former and the latter, in his season: he reserveth unto us the appointed weeks of the harvest. (Jeremiah 5:24); James 5:77Be patient therefore, brethren, unto the coming of the Lord. Behold, the husbandman waiteth for the precious fruit of the earth, and hath long patience for it, until he receive the early and latter rain. (James 5:7)). The grains grown were wheat, barley, rye, and millet. Orchards produced the vine, olive, and fig. Gardens grew beans, fitches, pease, lettuce, endive, leeks, garlic, onions, melons, cucumbers, cabbage, and so forth. The implements were the plow, harrow, and hoe, but these were crude. Grains were cut with the sickle, and the sheaves were threshed by treading with oxen, usually drawing sleds; while winnowing was done in sheets before the wind. Lands rested once in seven years (Lev. 25:1-71And the Lord spake unto Moses in mount Sinai, saying, 2Speak unto the children of Israel, and say unto them, When ye come into the land which I give you, then shall the land keep a sabbath unto the Lord. 3Six years thou shalt sow thy field, and six years thou shalt prune thy vineyard, and gather in the fruit thereof; 4But in the seventh year shall be a sabbath of rest unto the land, a sabbath for the Lord: thou shalt neither sow thy field, nor prune thy vineyard. 5That which groweth of its own accord of thy harvest thou shalt not reap, neither gather the grapes of thy vine undressed: for it is a year of rest unto the land. 6And the sabbath of the land shall be meat for you; for thee, and for thy servant, and for thy maid, and for thy hired servant, and for thy stranger that sojourneth with thee, 7And for thy cattle, and for the beast that are in thy land, shall all the increase thereof be meat. (Leviticus 25:1‑7)). The poor were allowed to glean (Lev. 19:9-109And when ye reap the harvest of your land, thou shalt not wholly reap the corners of thy field, neither shalt thou gather the gleanings of thy harvest. 10And thou shalt not glean thy vineyard, neither shalt thou gather every grape of thy vineyard; thou shalt leave them for the poor and stranger: I am the Lord your God. (Leviticus 19:9‑10); Deut. 24:1919When thou cuttest down thine harvest in thy field, and hast forgot a sheaf in the field, thou shalt not go again to fetch it: it shall be for the stranger, for the fatherless, and for the widow: that the Lord thy God may bless thee in all the work of thine hands. (Deuteronomy 24:19)).
