ופרש"י פה אל פה אמרתי לו לפרוש מן האשה שנא' ואתה פה עמוד עמדי ותימא א"כ למה נתרעמו ממה שפירש. וי"ל נתרעמו ממה שפירש קודם לכן שלא היה מצוה לו הקב"ה לפרוש אם לא שפירש מדעתו דקי"ל דבדרך שאדם רוצה לילך מוליכין אותו. ומתוך מעשה דאלדד ומידד ידעו מפי צפורה שפירש קודם לכן כדפרש"י ואז דברו בו: פה אל פה אדבר בו, “I speak to him mouth to mouth;” according to Rashi, G–d told Miriam and Aaron that it was He who had expressly told Moses to divorce his wife. At the revelation as related in Deuteronomy 5,28, G–d had told Moses to send the people home to their wives, whereas He had told him: “you stand here with Me.” If that was what had transpired already then, what did Miriam and Aaron get upset about now that Moses had separated from his wife? What other choice did he have? We may have to understand what transpired as follows. Moses had separated from his wife before being told to do so. Seeing that we have a rule that we are allowed to carry out our desires, i.e. permissible desires, בדרך שאדם רוצה ליליך מוליכין אותו, “G–d lets a person pursue the choice he makes concerning his lifestyle.” [otherwise what is free will all about? Ed.] Having heard that Tzipporah had told Eldod and Meydod that Moses had already separated from her earlier, before being commanded by G–d to so, Miriam and Aaron were upset about that. They were convinced that G–d would not have commanded him to do so, unless he had indicated that he was willing to do so even without being commanded to.
