'Song' in the Bible

Then Jehoiada put the oversight of the Lord’s temple into the hands of the Levitical priests, whom David had appointed over the Lord’s temple, to offer burnt offerings to the Lord as it is written in the law of Moses, with rejoicing and song ordained by David.

Then Hezekiah ordered that the burnt offering be offered on the altar. When the burnt offerings began, the song of the Lord and the trumpets began, accompanied by the instruments of David king of Israel.

The whole assembly was worshiping, singing the song, and blowing the trumpets—all of this continued until the burnt offering was completed.
