The overall lesson of Numbers 12 is not to lift yourself up above or at the expense of others. Miriam and Aaron presumed that their younger brother, Moses, had the same type of relationship with God as they enjoyed and complained that he was ruler over them. They had no idea how intimately God spoke with Moses until now.
The friends of God are those who trust the promises and testimony of God and want to communicate with God face to face, despite knowing how disastrous that could be for one’s casual observance of God. We can know God as one speaks to a friend, but once God calls you to be His friend, you life will never be the same.
Given an outside view of what the Adversary was allowed to do to ’Iyyob (Job), we can look down on the spiritual ignorance of his three friends and even of ’Iyyob’s statements in his defense. Rather, this is a powerful lesson on proverbially removing the “log” from one’s eye before looking for the “sawdust” in someone else’s.
