Exodus 23:14-19

“Three times a year you shall celebrate a feast to Me. You shall observe the Feast of Unleavened Bread; for seven days you are to eat unleavened bread, as I commanded you, at the appointed time in the month Abib, for in it you came out of Egypt. And none shall appear before Me empty-handed. Also you shall observe the Feast of the Harvest of the first fruits of your labors from what you sow in the field; also the Feast of the Ingathering at the end of the year when you gather in the fruit of your labors from the field. Three times a year all your males shall appear before the Lord GOD. “You shall not offer the blood of My sacrifice with leavened bread; nor is the fat of My feast to remain overnight until morning. “You shall bring the choice first fruits of your soil into the house of the LORD your God. “ Y ou are not to boil a young goat in the milk of its mother.
