|Hearing of the miracles HaShem has performed for the Beney Yisrael, Moshe's father-in-law, Yitro, arrives with Moshe's wife and sons, reuniting the family in the wilderness.|
Yitro is so impressed by Moshe's detailing of the Exodus from Egypt that he converts and joins the Jewish People. Seeing that the only judicial authority for the entire Jewish nation is Moshe himself, Yitro suggests that subsidiary judges be appointed to adjudicate the smaller matters, leaving Moshe free to attend to larger issues.
Moshe accepts his advice. The Beney Yisrael arrive at Mt. Sinay where the Torah is offered to them. After they accept, HaShem charges Moshe to instruct the people not to approach the mountain, and to prepare themselves for three days in order to receive the Torah. On the third day, amidst thunder and lightning, HaShem's voice emanates from the smoke-enshrouded mountain, and He begins speaking to the Jewish People, giving to them the Ten Commandments:
1.Believe in HaShem 2.Don't have other G-ds 3.Don't use HaShem's name in vain 4.Observe the Shabat 5.Honour your parents 6.Don't murder 7.Don't commit adultery 8.Don't kidnap 9.Don't testify falsely 10.Don't covet
After receiving the first two commandments, the Jewish People, overwhelmed by this experience of the Divine, request that Moshe relay HaShem's word to them. HaShem instructs Moshe to caution the Jewish People regarding their responsibility to be faithful to the One who spoke to them.
