'Burnt offerings' in the Bible

To what purpose does there come to me frankincense from Sheba, and the sweet cane from a far country? Your burnt-offerings are not acceptable, nor your sacrifices pleasing to me.

Thus says LORD of hosts, the God of Israel: Add your burnt-offerings to your sacrifices, and eat ye flesh.

For I spoke not to your fathers, nor commanded 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 round about Jerusalem, and from the land of Benjamin, and from the lowland, and from the hill-country, and from the South, bringing burnt-offerings, and sacrifices,

and have built the high places of Baal, to burn their sons in the fire for burnt-offerings to Baal, which I commanded not, nor spoke it, neither did it come into my mind.

neither shall the priests the Levites want a man before me to offer burnt-offerings, and to burn meal-offerings, and to do sacrifice continually.
