Exodus 23:16, 19

“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.

“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.
