'Burnt offerings' in the Bible

And though ye offer me burnt offerings and meat offerings, yet have I no pleasure therein. As for your fat thank offerings, I will not look upon them.

"What acceptable thing shall I offer unto the LORD? Shall I bow my knee to the high God? Shall I come before him with burnt offerings, and with calves of a year old?

And to love him with all the heart, and with all the mind, and with all the soul, and with all the strength. And to love a man's neighbor as himself, is a greater thing than all burnt offerings and sacrifices."
