'Burnt sacrifice' in the Bible

So he took his firstborn son, who was to succeed him as king, and offered him up as a burnt sacrifice on the wall. There was an outburst of divine anger against Israel, so they broke off the attack and returned to their homeland.

When he finished offering the burnt sacrifice, Jehu ordered the royal guard and officers, "Come in and strike them down! Don't let any escape!" So the royal guard and officers struck them down with the sword and left their bodies lying there. Then they entered the inner sanctuary of the temple of Baal.

He offered his burnt sacrifice and his grain offering. He poured out his libation and sprinkled the blood from his peace offerings on the altar.

King Ahaz ordered Uriah the priest, "On the large altar offer the morning burnt sacrifice, the evening grain offering, the royal burnt sacrifices and grain offering, the burnt sacrifice for all the people of Israel, their grain offering, and their libations. Sprinkle all the blood of the burnt sacrifice and other sacrifices on it. The bronze altar will be for my personal use."
