Moses begins making preparation for his final words to the people of Israel. God commands him to teach them a song, which appears in the next portion. It is this song that will bear witness to their covenant with God -- and that will testify against them, in the (likely) event that they become corrupted and sin.
It is interesting that God appointed a song as a witness to the covenant. Songs can be timeless; we still sing nursery rhymes that are centuries old, and that have lost their original meaning (mercifully, in some cases). Yet they can also contain lessons that are handed down from generation to generation.
Art, more generally, is exactly this kind of independent witness to civilization. It reflects contemporary thoughts and prejudices -- but can also serve as a basis for reflection on changing circumstances. So while Moses is channeling a warning from God, he is also giving purpose to art -- a humanistic message.
This is the portion that all journalists should love: the Torah tells the story of the 12 spies, only two of whom tell the truth when the other ten shade it in a negative away (perhaps to suit a political agenda that is opposed to Moses).
It's not that the ten "lying" spies misconstrue the facts about the Land of Israel; rather, they interject their opinions that the land is impossible to conquer, which strikes unnecessary terror into the hearts of the people.
We have many examples of such fake news today -- from the Iranian propaganda outlets spreading false claims that they are winning the war, to California politicians spreading false horror stories about ICE raids in L.A.
The people realize, too late, that they have been fooled, and once they are condemned to die in the desert, they try to rush into Israel -- only to be defeated by the inhabitants, as the spies predicted that they would be.
But as consolation, God gives the people new commandments -- focused on things they must ...
This week's portion discusses the procedure for lighting the menorah, the holy seven-branched lamp, in the Tabernacle (and later the Temple). It also describes an episode where the people crave meat, and God punishes them by giving it to them in excess. We also read the story of Miriam, Moses's sister, who is punished with the spiritual skin blemish of tzara'at for speaking about her brother, thus violating the prohibition against lashon hara (evil tongue).
I heard a fantastic sermon this week about the lighting of the menorah: that while only the priests were qualified to clean and purify the menorah, anyone could light it. A reminder that each of us can inspire others along the way.
This week we study the vow of the Nazirite; a reminder that sometimes trying to be too holy is excessive, and the best we can do is to be the best that we are.
