Exodus 23:11-15

but in the seventh year you shall let it rest and lie uncultivated, so that the needy of your people may eat; and whatever they leave the animal of the field may eat. You are to do the same with your vineyard and your olive grove.

“For 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 the stranger residing with you, may refresh themselves.

Now concerning everything which I have said to you, be careful; and do not mention the name of other gods, nor let them be heard from your mouth. Three National Feasts

“Three times a year you shall celebrate a feast to Me.

You shall keep 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 of Abib, for in that month you came out of Egypt. And no one is to appear before Me empty-handed.
