“Why then were you not afraid to speak against my servant Moses?" (v8). Moses’ siblings criticized him apparently due to a mixture of jealousy over his leadership (v2) and discomfort with his marriage to a foreign woman (v1). God Himself “came down in a pillar of cloud” and rebuked Aaron and Miriam, because they had stopped recognizing the unique relationship that Moses had with God as he led the people (v5). They had lost respect for Moses because they had lost their awe of God.
We should be amazed that God chooses to dwell among us by His Spirit. Through His Word and through leaders and each other, He continues to guide, correct, comfort, and encourage us.
