Rabbinic tradition teaches that when God spoke at Sinai, the world was silenced - birds did not sing, breezes did not rustle leaves in the trees. Out of that profound silence came the word, and were the world silent again, for even an instant, we could hear the everlasting echo of God's voice.
In one way that is a beautiful metaphor for the holiday of Shavuot. Among the holidays, it is “silent” in that no custom imposes itself on our imagination. There is no sukkah, no seder. It slips by, for many Jews, almost unnoticed. Yet the echoing voice makes it the central moment in our history. On Shavuot we celebrate the giving of the Torah, the establishment of the Jewish covenant.
The rabbis tell us that the Torah is the ketubah between God and the Jewish people. A ketubah is sometimes called a wedding contract, but it is better called a covenant. It enshrines sacred obligations. Jews are a covenantal people; we are bound to one another and to God by the idea of everlasting, mutual obligation. Sinai was the chuppah, and Shavuot is our anniversary.
On our anniversary we recall what made us a people. It is customary to stay up at night to study on Shavuot in order to demonstrate symbolically that we stand at the ready to receive the Torah. It is also a signal of acceptance and of passion.
Our tradition advises us to read the Torah as a love letter. One who receives a letter from a beloved reviews it again and again, searching each word and clause for significance, noting what is said and what remains unsaid. We read the Torah with the lens of the lover, dwelling over each word, unwilling to set it aside, certain that to study it once more will help us understand.
The Book of Ruth is read on this holiday because Ruth took upon herself the Jewish tradition in full. She accepted, as a true convert must, both the people and God. Israel embraces more than the individual’s relationship to the Divine; we are bound to one another. When Ruth declares to Naomi, "Your people shall be my people and your God my God," she epitomizes the covenantal message of mutual interdependence, past and future, the dual covenant of faith and of fate.
There is a custom to eat dairy foods on Shavuot, given for a variety of reasons, including the inventive idea that the laws of kashrut were unclear before the giving of the Torah and eating dairy was therefore less complicated. It may also be tied to the idea of eating lighter fare, which makes it easier to stay awake for the tikkun. Symbolism and practicality are at times symbiotic in ritual life.
The great Saadia Gaon taught that we are a nation only by virtue of our Torah. For a people dispersed throughout the world, the Torah was the one precious possession - containing our history, our values and our practice - that bound us one to the other. Shavuot is the moment that made us who we are. We celebrate, on this holiday, our relationship to God and to one another. As we hold the Torah aloft, we also celebrate our identity as Jews, eternal people of the covenant.
