'Burnt offering' in the Bible

The cart came to the field of Joshua of Beth-shemesh and stopped there near a large rock. The people of the city chopped up the cart and offered the cows as a burnt offering to the Lord.

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

Samuel was offering the burnt offering as the Philistines drew near to fight against Israel. The Lord thundered loudly against the Philistines that day and threw them into such confusion that they fled before Israel.

So Saul said, “Bring me the burnt offering and the fellowship offerings.” Then he offered the burnt offering.

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

I thought: The Philistines will now descend on me at Gilgal, and I haven’t sought the Lord’s favor. So I forced myself to offer the burnt offering.”
