Exodus 23:15-17 Evangelical Heritage Version (EHV)
15 You shall observe the Festival of Unleavened Bread.[a] For seven days you shall eat bread without yeast, as I commanded you, at the appointed time in the month of Abib (for during that month you came out from Egypt). No one is to appear before me empty-handed.
16 Next observe the Festival of Reaping[b] by presenting the first ripe produce of your labors, which you sow in the field.
Finally, observe the Festival of Ingathering,[c] at the end of the year, when you pick the fruits of your labors from the fields. 17 Three times a year all your males shall appear before the Lord God.
