'Burnt offerings' in the Bible

What unto me is the multitude of your sacrifices? saith Jehovah: I have had enough of the burnt-offerings of rams, and the fat of fed beasts; and I delight not in the blood of bullocks, or of lambs, or of he-goats.

Thou hast not brought me of thy sheep for burnt-offerings; neither hast thou honored me with thy sacrifices. I have not burdened thee with offerings, nor wearied thee with frankincense.

even them will I bring to my holy mountain, and make them joyful in my house of prayer: their burnt-offerings and their sacrifices shall be accepted upon mine altar; for my house shall be called a house of prayer for all peoples.
