'Burnt offering' in the Bible

The cart came to the field of Joshua of Beth-shemesh, and stopped there. In that place there was a large stone. They broke up the wood from the cart, and offered up the cows as a burnt offering to the LORD.

Then Samuel took a nursing lamb and offered it as a whole burnt offering to the LORD. Samuel cried out to the LORD on behalf of Israel, and the LORD answered him.

While Samuel was sacrificing the burnt offering, the Philistines approached to attack Israel. But that day the LORD thundered against the Philistines and threw them into panic, and they were defeated before Israel.

Saul said, "Bring the burnt offering and the peace offering to me," and he offered the burnt offering.

Just as he finished offering the burnt offering, Samuel arrived, and Saul went out to meet and greet him.

Saul replied, "When? I saw that the people were scattering from me, that you didn't come at the appointed time, and that the Philistines were assembling at Michmash. I thought, "The Philistines will come down against me at Gilgal but I've not sought the favor of the LORD,' so I forced myself to offer the burnt offering."
