Exodus 23:14-19

14“Three times in the year you are to ce­lebrate a festival for Me.

15You are to observe the Feast of Matzot. For seven days you will eat matzot as I commanded you, at the time appointed in the month Aviv, for that is when you came out from Egypt. No one is to appear before Me empty-handed.

16Also you are to observe the Feast of Harvest, the firstfruits of your labors that you sow in the field, as well as the Feast of the Ingathering at the end of the year, when you gather your crops from the field.

17Three times in the year all your men are to appear before Adonai Elohim.

18“Do not offer the blood of My sacrifice with hametz. Nor is the fat of My feast to remain out all night until the morning.

19Bring the choicest firstfruits of your land into the House of Adonai your God. “Do not boil a kid in its mother’s milk.
