It is very significant that this parsha is named “Jethro” and not “The Ten Words” or Commandments that it contains. In a sense the advice that Jethro gives Moshe is just as important as the Ten Commandments because it shows YHWH’s plan.
First Moshe needs to keep himself from getting exhausted. Then he needs to set the leaders of the nation of Israel on the right course, and encourage discussion between them and the people. And finally, the people need to understand that when Abba YHWH says “Don’t go there or you will die” that He means business! Only then, with every one playing their appropriate part and in the right frame of mind, can the Commandments be given.
