'Sacrifices' in the Bible

"And on the day of your joy and in your appointed times, at the beginning of your months, you will blow on the trumpets in addition to your burnt offerings and in addition to the sacrifices of your fellowship offerings. And they will be as a memorial for you {before} your God; I [am] Yahweh your God."

And they invited the people to the sacrifices of their gods, and the people ate and worshiped their gods.
