Exodus 23:14-16 Modern English Version (MEV)
The Three Annual Feasts
14 Three times in the year you must celebrate a feast to Me.
15 You shall observe the Feast of Unleavened Bread. For seven days you shall eat unleavened bread, as I commanded you, in the appointed time of the month Aviv, for in it you came out from Egypt.
No one shall appear before Me empty-handed.
16 You shall observe the Feast of Harvest, the first fruits of your labors, which you have sown in the field.
You shall observe the Feast of Ingathering at the end of the year, when you have gathered in the fruit of your labors from the field.
