We don’t think of music this way. There can be songs of love, joy, hardship, help, but a song that testifies against a people? From the Lord?
And that’s exactly what took place.
As Moses was passing the baton of leadership to Joshua, the Lord instructed them to write down a song. Knowing that the heart of Israel would soon adulterate themselves and seek other gods, the Lord gave them a song to remember and testify to Him.
“I will certainly hide My face on that day because of the evil they have done by turning to other gods. Therefore write down this song for yourselves and teach it to the Israelites; have them recite it, so that this song may be a witness for Me against the Israelites.” (v. 19)
“And when many troubles and afflictions come to them, this song will testify against them, because their descendants will not have forgotten it” (v. 21)
And after Moses is told to do this, he writes it down. And once again instructs Joshua,
“Be strong and courageous, for you will bring the Israelites into the land I swore to them, and I will be with you” (v. 23).
Sounds like there were going to be many scary, “impossible” looking situations that they were going to face that needed this encouragement so much.
But what about the song? The song of testimony against the Israelites?
To read it, go to Deuteronomy 32.
