“Now therefore write ye this song for you, and teach it the children of Israel: put it in their mouths, that this song may be a witness for me against the children of Israel.” (Deuteronomy 31:19)
The book of Psalms was essentially a song book for Old and New Testament Jews, while other songs are scattered throughout Scripture written by a variety of prophets and leaders. Our text tells us that the Lord commanded Moses and Joshua to write aspects of the Law and details of God’s dealings with the nation, as well as His promise of judgment should they disobey—in a song.
This song would serve several functions. First, it would be a memory device. “It shall not be forgotten out of the mouths of their seed” (v. 21). Those who have been around good church music probably know many portions of Scripture set to music, including the grand old hymns of the faith that are frequently conglomerates of many verses around a doctrinal theme. Many of us probably have memorized without trying, and maybe without realizing, many, many Scripture verses. In fact, this may be the very best way to build biblical principles into the lives of our children.
The second function of Moses’ song would be to convict those in disobedience (32:7, 47, etc.). As with the people of Israel, our hearts should be receptive to the teachings contained within the songs that we know.
Unfortunately, Israel seldom listened, even to those songs they had memorized. Thus, the third and evidently primary function of this song was to “testify against them as a witness” (31:21). Much of this song carefully explains their coming apostasy and inevitable judgment. No doubt many remembered this song and its message with tears as they marched into captivity, unable to charge God with unfaithfulness. JDM
