Exodus 23:13

9 Do not oppress a foreign resident, since you yourselves know how it feels to be foreigners; for you were foreigners in the land of Egypt.

10 For six years you are to sow your land and gather its produce,

11 but in the seventh year you must let it rest and lie fallow, so that the poor among your people may eat from the field and the wild animals may consume what they leave. Do the same with your vineyard and olive grove.

12 For six days you are to do your work, but on the seventh day you must cease, so that your ox and your donkey may rest and the son of your maidservant may be refreshed, as well as the foreign resident.

13 Pay close attention to everything I have said to you. You must not invoke the names of other gods; they must not be heard on your lips.

14 Three times a year you are to celebrate a feast to Me.

15 You are to keep the Feast of Unleavened Bread as I commanded you: At the appointed time in the month of Abib you are to eat unleavened bread for seven days, because that was the month you came out of Egypt. No one may appear before Me empty-handed.

16 You are also to keep the Feast of Harvest with the firstfruits of the produce from what you sow in the field. And keep the Feast of Ingathering at the end of the year, when you gather your produce from the field.

17 Three times a year all your males are to appear before the Lord GOD.
