'Sacrificial' in the Bible

“As for you, O house of Israel,” thus says the Lord God, “Go, let everyone serve his idols; but later you shall most certainly listen to Me, and you shall no longer profane My holy name with your gifts and with your idols.

“Son of man, this is what the Lord God says: Tell every kind of bird and all the wild animals: Assemble and come! Gather from all around to My sacrificial feast that I am slaughtering for you, a great feast on the mountains of Israel; you will eat flesh and drink blood.

You will eat fat until you are satisfied and drink blood until you are drunk, at My sacrificial feast that I have prepared for you.

Only the prince may sit in it to eat a sacrificial meal before the Lord; he will enter by way of the porch of the gate and will go out by the same way."
