Exodus 23:10-22
English Standard Version
Chapter 23
10"For six years you shall sow your land and gather in its yield, 11but the seventh year you shall let it rest and lie fallow, that the poor of your people may eat; and what they leave the beasts of the field may eat. You shall do likewise with your vineyard, and with your olive orchard.
14"Three times in the year you shall keep a feast to me.
15You shall keep the Feast of Unleavened Bread. As I commanded you, you shall eat unleavened bread for seven days at the appointed time in the month of Abib, for in it you came out of Egypt. None shall appear before me empty-handed.
16You shall keep the Feast of Harvest, of the firstfruits of your labor, of what you sow in the field. You shall keep the Feast of Ingathering at the end of the year, when you gather in from the field the fruit of your labor.
17Three times in the year shall all your males appear before the Lord God.
