'Burnt offering' in the Bible

and build an altar to the LORD your God on top of this stronghold in an orderly manner. Then take the second bull and offer it as a burnt offering using the wood from the Asherah that you'll be cutting down."

then if I return from the Ammonites without incident, whatever comes out the doors of my house to meet me will become the LORD's, and I will offer it up as a burnt offering."

The angel of the LORD answered Manoah, "If you detain me, I won't be eating your food, but if you prepare a burnt offering, you'll be making a sacrifice to the LORD." The angel of the LORD said this because Manoah didn't know that he was the angel of the LORD.

When the burnt offering was engulfed in flames that sprang up from the altar toward heaven, the angel of the LORD ascended in the flame that came from the altar. When Manoah and his wife observed this, they collapsed on their faces to the ground.

But his wife replied to him, "If the LORD had intended to kill us, he wouldn't have accepted a burnt offering and a grain offering from us, he wouldn't have shown us all these things, and he wouldn't have permitted us to hear things like this, now would he?"
