“Yahweh spoke to Moses on Mount Sinai. Speak to the people of Israel, ‘when you enter into the land that I am giving you, the land shall observe a Sabbath for Yahweh. Six years you shall sow your field, and six years you shall prune your vineyard, and gather in their yield. But in the seventh year there shall be a Sabbath of complete rest for the land, a Sabbath for Yahweh. You shall not sow your field or prune your vineyard. You shall not reap the after-growth of your harvest or gather the grapes of your un-pruned vine. It shall be a year of complete rest for the land. You may eat what the land yields during its Sabbath. You, your male and female slaves, your hired and bound laborers who live with you. For your livestock also, and for the wild animals in your land all its yield shall be for food.”
This time Yahweh spoke to Moses on Mount Sinai. After you get to the Promised Land, you must remember that the land belongs to Yahweh. Therefore you have to give it a rest every seven years as was mentioned in Exodus, chapter 23. You can sow your field and prune your vines for six years, but in the seventh year there shall be a complete rest for the land, a Sabbath for Yahweh. You can live off the land and your livestock. This applies to all in your household, your family, your slaves, and your laborers. For six years you work hard in the field and on the seven year, you let it grow wild.
