Numbers 12:1 And Miriam and Aaron spake against Moses because of the Ethiopian woman whom he had married: for he had married an Ethiopian woman.
[Patriarchs & Prophets pp 383>384] Though called a “Cushite woman” (Numbers 12:1, R.V.), the wife of Moses was a Midianite, and thus a descendant of Abraham. In personal appearance she differed from the Hebrews in being of a somewhat darker complexion. Though not an Israelite, Zipporah was a worshiper of the true God. She was of a timid, retiring disposition, gentle and affectionate, and greatly distressed at the sight of suffering; and it was for this reason that Moses, when on the way to Egypt, had consented to her return to Midian. He desired to spare her the pain of witnessing the judgments that were to fall on the Egyptians.
When Zipporah rejoined her husband in the wilderness, she saw that his burdens were wearing away his strength, and she made known her fears to Jethro, who suggested measures for his relief. Here was the chief reason for Miriam's antipathy to Zipporah. Smarting under the supposed neglect shown to herself and Aaron, she regarded the wife of Moses as the cause, concluding that her influence had prevented him from taking them into his counsels as formerly. Had Aaron stood up firmly for the right, he might have checked the evil; but instead of showing Miriam the sinfulness of her conduct, he sympathized with her, listened to her words of complaint, and thus came to share her jealousy.
Their accusations were borne by Moses in uncomplaining silence. It was the experience gained during the years of toil and waiting in Midian—the spirit of humility and long-suffering there developed—that prepared Moses to meet with patience the unbelief and murmuring of the people and the pride and envy of those who should have been his unswerving helpers.
1st Corinthians 10:10 Neither murmur ye, as some of them also murmured, and were destroyed of the destroyer. 11 Now all these things happened unto them for examples: and they are written for our admonition, upon whom the ends of the world are come.
May God add His blessing to the study of His word. "Good night" and God bless!
