In addition to in the Psalms, Scripture records the lyrics of several key songs at considerable length. The song in Deuteronomy 32 has 43 verses; the songs in both Judges 5 and Isaiah 5 have 30 verses; and the song in 2 Samuel 22 has 50 verses.
Second Samuel 22:2-51 and Deuteronomy 32:1-43, the two longest songs in Scripture (outside of the Psalms), share a common feature that is noteworthy—Scripture records that both of these songs were spoken:
Deuteronomy 31:30 And Moses spake in the ears of all the congregation of Israel the words of this song, until they were ended.
Deuteronomy 32:44 And Moses came and spake all the words of this song in the ears of the people, he, and Hoshea the son of Nun.
2 Samuel 22:1 And David spake unto the LORD the words of this song in the day that the LORD had delivered him out of the hand of all his enemies, and out of the hand of Saul.
Strikingly, both 2 Samuel 22 and Deuteronomy 32 lack any mention that these songs were sung on the first occasions of their use.
Moreover, David spoke the words of his song “unto the LORD” (2 Sam. 22:1).
Based on this data, we learn that oral recitation of the lyrics of entire songs is biblical, both to one another (cf. Moses to the people [Deut. 31:30; 32:44]) and to the Lord (2 Sam. 22:1)!
