And keep the Feast of Ingathering at the end of the year, when you gather your produce from the field. 17Three times a year all your males are to appear before the Lord GOD. 18You must not offer the blood of My sacrifices with anything leavened, nor may the fat of My feast remain until morning. 19Bring the best of the firstfruits of your soil to the house of the LORD your God.
