'Burnt offering' in the Bible

Build a well-constructed altar to the Lord your God on the top of this rock. Take the second bull and offer it as a burnt offering with the wood of the Asherah pole you cut down.”

whatever comes out of the doors of my house to greet me when I return in peace from the Ammonites will belong to the Lord, and I will offer it as a burnt offering.”

The Angel of the Lord said to him, “If I stay, I won’t eat your food. But if you want to prepare a burnt offering, offer it to the Lord.” For Manoah did not know He was the Angel of the Lord.

But his wife said to him, “If the Lord had intended to kill us, He wouldn’t have accepted the burnt offering and the grain offering from us, and He would not have shown us all these things or spoken to us now like this.”
