'Burnt sacrifice' in the Bible

They went to King Hezekiah and said: "We have purified the entire temple of the Lord, including the altar of burnt sacrifice and all its equipment, and the table for the Bread of the Presence and all its equipment.

Then the priests slaughtered them. They offered their blood as a sin offering on the altar to make atonement for all Israel, because the king had decreed that the burnt sacrifice and sin offering were for all Israel.

Hezekiah ordered the burnt sacrifice to be offered on the altar. As they began to offer the sacrifice, they also began to sing to the Lord, accompanied by the trumpets and the musical instruments of King David of Israel.

The entire assembly worshiped, as the singers sang and the trumpeters played. They continued until the burnt sacrifice was completed.
