Parshat Yitro has much to teach. It's the chapter of the"Top Ten" Commandments, or more properly, the Ten Utterances, so called because these commandments were actually spoken by G-d. Not that we could stand listening to them.
Famously, the Voice of G-d was so powerful, that the people fainted dead away when
the Master of the Universe either spoke all ten at once, or uttered the first two, either simultaneously or consecutively.
