'Burnt offerings' in the Bible

Why does frankincense come to Me from Sheba, and the sweet cane from a far country? Your burnt offerings are not pleasing, nor your sacrifices sweet to Me.

So says Jehovah of Hosts, the God of Israel: Put your burnt offerings to your sacrifices, and eat flesh.

For I did not speak to your fathers, nor command them in the day that I brought them out of the land of Egypt, concerning burnt offerings or sacrifices.

And they shall come from the cities of Judah, and from the places about Jerusalem, and from the land of Benjamin, and from the plain, and from the mountains, and from the south, bringing burnt offerings, and sacrifices, and grain offerings, and incense, and bringing sacrifices of praise to the house of Jehovah.

They have also built the high places of Baal, to burn their sons with fire for burnt offerings to Baal, which I never commanded nor spoke, nor did it come into My mind.

nor shall the priests the Levites lack a man before Me to offer burnt offerings, and to kindle grain offerings, and to do sacrifice forever.
