'Burnt Offerings' in the Bible

They brought the ark of the Lord and set it in its place inside the tent David had set up for it. Then David offered burnt offerings and fellowship offerings in the Lord’s presence.

The king answered Araunah, “No, I insist on buying it from you for a price, for I will not offer to the Lord my God burnt offerings that cost me nothing.” David bought the threshing floor and the oxen for 20 ounces of silver.

He built an altar to the Lord there and offered burnt offerings and fellowship offerings. Then the Lord answered prayer on behalf of the land, and the plague on Israel ended.
