Exodus 23:14-19

“Three times each year you must hold a feast to honor me. You must celebrate the Feast of Unleavened Bread in the way I commanded you. For seven days you must eat bread that is made without yeast at the set time during the month of Abib, the month when you came out of Egypt. No one is to come to worship me without bringing an offering. “You must celebrate the Feast of Weeks. Offer to God the first things you harvest from the crops you planted in your fields. “You must celebrate the Feast of Shelters in the fall, when you gather all the crops from your fields. “So three times during every year all your males must come to worship the LORD God. “You must not offer animal blood along with anything that has yeast in it. “You must not save any of the fat from the sacrifice for the next day. “You must bring the best of the firstfruits of your land to the Holy Tent of the LORD your God. “You must not cook a young goat in its mother’s milk.
