Exodus 34:22-26

“Keep the Feast of Weeks with the first cutting of the wheat harvest, and the Feast of Ingathering at the turn of the year. “All your men are to appear before the Master, the GOD of Israel, three times a year. You won’t have to worry about your land when you appear before your GOD three times each year, for I will drive out the nations before you and give you plenty of land. Nobody’s going to be hanging around plotting ways to get it from you. “Don’t mix the blood of my sacrifices with anything fermented. “Don’t leave leftovers from the Passover Feast until morning. “Bring the finest of the firstfruits of your produce to the house of your GOD. “Don’t boil a kid in its mother’s milk.”
