Numbers 12:9

“And the anger of the Lord was kindled against them, etc.] Which might be visible by some outward token, as by lightning from the cloud, or, however, what follows was sufficient to show it: and he departed; from the door of the tabernacle of the congregation, where he had stood in the pillar of cloud for some time; but as soon as he had given his testimony of Moses, and expressed his displeasure at Aaron and Miriam, he went away directly from them; not staying to hear what they had to say for themselves, which was a plain indication of his anger against them.”

“Miriam, as a prophetess (compare Exodus 15:20-21) no less than as the sister of Moses and Aaron, took the first rank among the women of Israel; and Aaron may be regarded as the ecclesiastical head of the whole nation. But instead of being grateful for these high dignities they challenged the special vocation of Moses and the exclusive authority which God had assigned to him. Miriam was the instigator, from the fact that her name stands conspicuously first Numbers 12:1, and that the punishment Numbers 12:10 fell on her alone. She probably considered herself as supplanted, and that too by a foreigner. Aaron was misled this time by the urgency of his sister, as once before Exodus 32:0 by that…”

“He departed - From the door of the tabernacle, in token of his great displeasure, not waiting for their answer. The removal of God's presence from us, is the saddest token of his displeasure. And he never departs, till we by our sin and folly drive him from us. Numbers 12:10”

“12:9-16 Miriam bore the brunt of God’s wrath (see study note on 12:1-2). Once Aaron saw what had happened to her, he admitted his error and sought Moses’ intercession (cp. 11:2). Both Moses and the Lord accepted Aaron’s confession.”
