Miriam and Aaron criticize Moses for marrying a Cushite woman, accusing him of monopolizing God's revelation. They are jealous of Moses' leadership role. Moses remains patient and meek in response. God hears their criticism and punishes Miriam with leprosy to demonstrate Moses' unique authority and status as prophet. Commentators note the siblings' pride and envy contrasted with Moses' humility, and discuss the marriage and its significance.
