10 And the cloud was moved from over the Tent; and straight away Miriam became a leper, as white as snow: and Aaron, looking at Miriam, saw that she was a leper. 11 Then Aaron said to Moses, O my lord, let not our sin be on our heads, for we have done foolishly and are sinners. 12 Let her not be as one dead, whose flesh is half wasted when he comes out from the body of his mother. 13 And Moses, crying to the Lord, said, Let my prayer come before you, O God, and make her well. 14 And the Lord said to Moses, If her father had put a mark of shame on her, would she not be shamed for seven days? Let her be shut up outside the tent-circle for seven days, and after that she may come in again. 15 So Miriam was shut up outside the tent-circle for seven days: and the people did not go forward on their journey till Miriam had come in again. 16 After that, the people went on from Hazeroth and put up their tents in the waste land of Paran.

Commentary on Numbers 12:10-16

(Read Numbers 12:10-16)

The cloud departed, and Miriam became leprous. When God goes, evil comes: expect no good when God departs. Her foul tongue, as Bishop Hall says, was justly punished with a foul face. Aaron, as priest, was judge of the leprosy. He could not pronounce her leprous without trembling, knowing himself to be equally guilty. But if she was thus punished for speaking against Moses, what will become of those who sin against Christ? Aaron, who joined his sister in speaking against Moses, is forced for himself and his sister, to beseech him, and to speak highly of him whom he had so lately blamed. Those who trample upon the saints and servants of God, will one day be glad to make court to them. It is well when rebukes produce confession of sin and repentance. Such offenders, though corrected and disgraced, shall be pardoned. Moses made it appear, that he forgave the injury done him. To this pattern of Moses, and that of our Saviour, who said, "Father, forgive them," we must conform. A reason is given for Miriam's being put out of the camp for seven days; because thus she ought to accept the punishment of her sin. When under the tokens of God's displeasure for sin, it becomes us to take shame to ourselves. This hindered the people's progress in their march forward towards Canaan. Many things oppose us, but nothing so hinders us in the way to heaven, as sin.
