Sinai and the Ten Commandments

Yitro contains the theophany at Sinai, the founding covenant scene of the Torah, and the first of the two Torah versions of the Ten Commandments (the second in Vaetchanan). It is customarily read on the Shabbat associated with the giving of the law, and the congregation traditionally stands for its recitation. The moment of revelation at Sinai anchors the Jewish understanding of the Torah as divinely given and is commemorated at the festival of Shavuot.

The two Torah versions of the Ten Commandments, this one in Yitro and the second in Vaetchanan near the end of Deuteronomy, differ in small but debated wording, most famously over the Sabbath commandment, which Exodus grounds in the six days of creation and Deuteronomy grounds in the exodus from Egyptian slavery; rabbinic tradition resolved the discrepancy with the teaching that both versions were spoken simultaneously in a single divine utterance beyond ordinary human speech, a formula meant to hold two texts together rather than to explain the difference away. Sinai's status as the Torah's central theophany is marked liturgically by the custom of standing for the reading of the commandments in many congregations, even though halakhic authorities have historically debated whether singling them out this way risks suggesting they carry more weight than the rest of the Torah's six hundred and thirteen commandments, a concern that led some communities to discontinue the practice in antiquity precisely to avoid that implication.
