Exodus 23:18

¹⁶ You are also to keep the Feast of Harvest with the firstfruits of the produce from what you sow in the field. And keep the Feast of Ingathering at the end of the year, when you gather your produce from the field.

¹⁷ Three times a year all your males are to appear before the Lord GOD.

You must not offer the blood of My sacrifices with anything leavened, nor may the fat of My feast remain until morning.

¹⁹ Bring the best of the firstfruits of your soil to the house of the LORD your God. You must not cook a young goat in its mother’s milk.

²⁰ Behold, I am sending an angel before you to protect you along the way and to bring you to the place I have prepared.

This was said to Israel at a particular time, so it is wise to read it together with the surrounding text. Do read the surrounding verses too, because the context often says more than a single verse.
