And when many troubles and afflictions have come upon them,

Israel’s future rebellion would bring covenant judgment, including defeat, oppression, and exile. These hardships were not unforeseen but were the consequences of abandoning the God who had brought them into the land.

Deu 28:45-48 All these curses will come upon you. They will pursue you…
Lev 26:14-17 If, however, you fail to obey Me and to carry out…

The Song of Moses would preserve God’s warning and stand as a witness that Israel had been told the results of disobedience before they occurred.

Isa 59:12 For our transgressions are multiplied before You,…
Jer 14:7 Although our iniquities testify against us, O LORD,…

Deu 11:19 Teach them to your children, speaking about them…

Gen 6:5 Then the LORD saw that the wickedness of man…
Jer 17:9 The heart is deceitful above all things and beyond cure.…

The land remained God’s promised gift to the descendants of Abraham, Isaac, and Jacob, yet life in it required faithful obedience. God would keep His promise while also judging Israel’s sin.

Teaching Points
The Power of Remembrance
The song serves as a tool for remembrance, reminding the Israelites of God's laws and their covenant with Him. We should also use Scripture to remind ourselves of God's promises and our commitments.

God's Omniscience
God knows the hearts and future actions of His people. We should live with the awareness that nothing is hidden from God, and strive to align our actions with His will.

The Role of Warnings
Just as the song warns the Israelites of the consequences of disobedience, we should heed the warnings in Scripture to avoid spiritual pitfalls.

Generational Faithfulness
The song is meant to be remembered by future generations. We have a responsibility to pass down our faith and the truths of Scripture to the next generation.

The Certainty of God's Promises

(21) This song . . . shall not be forgotten out of the mouths of their seed.--And it is not forgotten now. St. Paul made special use of it in the last days of the second Temple. This song is a favourite piece of Hebrew poetry to this day. Rashi observes: "This is a promise to Israel that the law shall not be utterly forgotten by their seed."

I know their imagination.--Heb., yetzer, the same word employed in Genesis 6:5; Genesis 8:21. It is the word commonly used in Rabbinical literature for the evil nature or good nature in any man. The nature which they are forming, or making, this day, would be a literal rendering of the sentence in this verse. And yet with all this, He made Balaam say, "He hath not beheld iniquity in Jacob nor seen perverseness in Israel" (Numbers 23:21). Comp. 1Chronicles 28:9, "The Lord . . . understandeth all the imaginations of the thoughts," and Psalm 103:14, "He knoweth our frame (yetzer); He remembereth that we are dust." . . .

God foresees Israel’s future failures, yet in mercy provides a song that will echo through generations, calling His people to repentance. Troubles serve as loving discipline, the song serves as a faithful witness, and God’s foreknowledge showcases His steadfast commitment to the covenant He swore.
