Reflect for a moment on the rich and diverse means that God granted to Israel to help them remember what he had done to deliver them, and the nature of the covenant they had pledged themselves to obey. There was the tabernacle itself (later the temple), with its carefully prescribed rites and feasts: the covenant was not an abstract philosophical system, but was reflected in regular religious ritual. The nation was constituted in such a way that the Levites were distributed amongst the other tribes, and the Levites had the task of teaching the Law to the rest of the people. The three principal high feasts were designed to gather the people to the central tabernacle or temple, where both the ritual and the actual reading of the Law were to serve as powerful reminders (Deut. 31:11). From time to time God sent specially endowed judges and prophets, who called the people back to the covenant. Families were carefully taught how to pass on the inherited history to their children, so that new generations that had never seen the miraculous display of God’s power at the time of the Exodus would nevertheless be fully informed of it and own it as theirs. Moreover, blessings from God would attend obedience, and judgment from God would attend disobedience, so that the actual circumstances of the community were supposed to elicit reflection and self-examination. Legislation was passed to foster a sense of separateness in the fledgling nation, erecting certain barriers so that the people would not easily become contaminated by the surrounding paganism. Unique events, like the antiphonal shouting at Mounts Gerizim and Ebal at the time of entering the land (see June 22 meditation), were supposed to foster covenant fidelity in the national memory. But now God adds one more device. Precisely because God knows that in due course the people will rebel anyway, he instructs Moses to write a song of telling power that will become a national treasure — and a sung testimony against themselves (Deut. 31:19-22). Someone has said, “Let me write the songs of a nation, and I care not who writes its laws.” The aphorism is overstated, of course, but insightful nonetheless. That is the purpose of the next chapter, Deuteronomy 32. The Israelites will learn, as it were, a national anthem that will speak against them if they shut down all the other God-given calls to remember and obey. What devices, in both Scripture and history, has God graciously given to help the heirs of the new covenant remember and obey? Meditate on them. How have you used them? What songs do we sing to put this principle into practice, that teach the people of God matters of irrevocable substance beyond mere sentimentalism?
