12:1 And Miriam and Aaron spake against Moses because of the Ethiopian woman whom he had married: for he had married {a} an Ethiopian woman.
(a) Zipporah, Moses' wife, was a Midianite, and because Midian bordered on Ethiopia, it is sometimes referred to in the scriptures by this name.
12:1 Miriam - Miriam seems to be first named, because she was the first mover of the sedition; wherefore she is more eminently punished. The Ethiopian - Either, Zipporah, who is here called an Ethiopian, in the Hebrew a Cushite, because she was a Midianite: the word Cush being generally used in scripture, not for Ethiopia properly so called below Egypt, but for Arabia. If she be meant, probably they did not quarrel with him for marrying her, because that was done long since, but for being swayed by her and her relations, by whom they might think he was persuaded to chose seventy rulers, by which co - partnership in government they thought their authority and reputation diminished. And because they durst not accuse God, they charge Moses, his instrument, as the manner of men is. Or, some other woman, whom he married either whilst Zipporah lived, or rather because she was now dead, though that, as many other things, be not recorded. For, as the quarrel seems to be about his marrying a stranger, it is probable it was a fresh occasion about which they contended. And it was lawful for him as well as any other to marry an Ethiopian or Arabian woman, provided she were, a sincere proselyte.
12:1-9 The patience of Moses was tried in his own family, as well as by the people. The pretence was, that he had married a foreign wife; but probably their pride was hurt, and their envy stirred up, by his superior authority. Opposition from our near relations, and from religious friends, is most painful. But this is to be looked for, and it will be well if in such circumstances we can preserve the gentleness and meekness of Moses. Moses was thus fitted to the work he was called to. God not only cleared Moses, but praised him. Moses had the spirit of prophecy in a way which set him far above all other prophets; yet he that is least in the kingdom of heaven, is greater than he; and our Lord Jesus infinitely excels him, Heb 3:1. Let Miriam and Aaron consider whom it was they insulted. We have reason to be afraid of saying or doing any thing against the servants of God. And those are presumptuous indeed who are not afraid to speak evil of dignities, 2Pe 2:10. The removal of God's presence is the surest and saddest token of God's displeasure. Woe to us, if he depart! he never departs, till by sin and folly we drive him from us.
