Hath planted a vineyard This and the former dispensation were generally convenient, but more necessary in the beginning of their settlement in Canaan, for the encouragement of those who should build houses or plant vineyards, which were chargeable to them, and beneficial to the commonwealth. Eaten of it Hebrew, made it common; namely, for the use of himself, and family, and friends, which it was not till the fifth year.
