Mary and Aaron murmur against Moses, whom God praises above other prophets. Mary being struck with leprosy, Aaron confesses his fault. Moses prays for her, and after seven days’ separation from the camp, she is restored.

¹ And Miriam and Aaron spoke against Moses, because of his wife, an Ethiopian,¹²

1. 12:1Notice that Miriam’s name is listed first. This indicates that she was putting herself above Aaron as well as Moses, and it is a foreshadowing of those women who wish to put themselves above men by claiming to be ordained as Bishops and priests. Notice also that they first denigrate Moses by criticizing him unfairly. Then they try to life themselves up.(Conte)
2. 12:1Ethiopian: Sephora the wife of Moses was of Madian, which bordered upon the land of Chus or Ethiopia: where note, that the Ethiopia here spoken of is not that of Africa but that of Arabia.(Challoner)

² and they said: “Has the Lord spoken only through Moses? Has he not also spoken similarly to us?” And when the Lord had heard this,¹

1. 12:2This event was a foreshadowing of the rebellion in the Church against proper Church authority, against the authority of the Pope over the Bishops, against the authority of the Pope and Bishops over priests, deacons, and religious, and against the teaching of the Church that women cannot be Pope, Cardinal, Bishop, or priest in the Church. Miriam speaks as if she were equal to Moses in his role over Israel, just as some women speak as if they could be ordained as priests or Bishops, or as if it could ever be God’s will for them to lead men. God rebukes Aaron and Miriam for disdaining the roles given to each of them by God and for desiring a role not given to them. Notice also that even Miriam and Aaron know that God speaks to them, but through Moses. Yet they ignore that difference.(Conte)

³ (for Moses was a man exceedingly meek, beyond all the men who were living upon the earth)¹

1. 12:3Exceeding meek: Moses being the meekest of men, would not contend for himself; therefore, God inspired him to write here his own defence: and the Holy Spirit, whose dictate he wrote, obliged him to declare the truth, though it was so much to his own praise.(Challoner)

⁴ immediately he spoke to him, and to Aaron and Miriam, “Go out, you three only, to the tabernacle of the covenant.” And when they had gone out,

⁵ the Lord descended in a column of cloud, and he stood at the entrance of the tabernacle, calling to Aaron and Miriam. And when they had advanced,

⁶ he said to them: “Listen to my words. If there will be among you a prophet of the Lord, I will appear to him in a vision, or I will speak to him through a dream.

⁷ But it is not so with my servant Moses, who is the most faithful in all my house.

⁸ For I speak with him mouth to mouth, and plainly. And not through enigmas and figures does he perceive the Lord. Therefore, why were you not afraid to disparage my servant Moses?”

⁹ And being angry against them, he went away.

¹⁰ Likewise, the cloud which was over the tabernacle withdrew. And behold, Miriam appeared to be white with a leprosy, like snow. And when Aaron had looked upon her, and he had seen the spreading of the leprosy,

¹¹ he said to Moses: “I beg you, my lord, not to impose upon us this sin, which we have committed foolishly.

¹² Do not let this one be like one who is dead, or like an abortion that has been cast from the womb of her mother. Behold, half of her flesh is already consumed by leprosy.”

¹³ And Moses cried out to the Lord, saying, “O God, I beg you: heal her.”

¹⁴ And the Lord answered him: “If her father had spit on her face, should she not have been filled with shame for at least seven days? Let her be separated, outside the camp, for seven days, and after that, she will be called back.”

¹⁵ And so Miriam was excluded from the camp for seven days. And the people did not move from that place, until Miriam was called back.
