10 "You shall sow your land for six years and gather in its yield, 11 but on the seventh year you shall let it rest and lie fallow, so that the needy of your people may eat; and whatever they leave the beast of the field may eat. You are to do the same with your vineyard and your olive grove.
12 "Six days you are to do your work, but on the seventh day you shall cease from labor so that your ox and your donkey may rest, and the son of your female slave, as well as your stranger, may refresh themselves.
13 "Now concerning everything which I have said to you, be on your guard; and do not mention the name of other gods, nor let them be heard from your mouth.
14 "Three times a year you shall celebrate a feast to Me. 15 "You shall observe the Feast of Unleavened Bread; for seven days you are to eat unleavened bread, as I commanded you, at the appointed time in the month Abib, for in it you came out of Egypt And none shall appear before Me empty-handed. 16 "Also you shall observe the Feast of the Harvest of the first fruits of your labors from what you sow in the field; also the Feast of the Ingathering at the end of the year when you gather in the fruit of your labors from the field. 17 "Three times a year all your males shall appear before the Lord GOD.
