And Aaron said unto Moses, alas, my lord!.... The word for "alas" is generally interpreted by the Jewish writers as a note of beseeching and entreating, as it is here by the Targums of Onkelos and Jonathan,"I beseech thee, my lord,''or "upon me, my lord" (k), be all the blame; such was his tenderness to his sister, and the compassion he had on her; and such reverence and respect did he show to Moses his brother, though younger than he, because of his superior dignity as a prophet, and chief magistrate, and prime minister, and servant of the Lord, calling him "my lord":

I beseech thee, lay not the sin upon us; the punishment of it, bear not hard upon us, or suffer us to be punished in a rigorous manner, without interceding to the Lord for us, for the abatement of removal of it; such a powerful and prevailing interest he knew he had with God, that by his prayers their punishment would be mitigated, or not laid, or, if laid, removed:

wherein we have done foolishly, and wherein we have sinned; he owns they had sinned, but suggests, and so he would have it understood, that it was not through malice, and purposely and presumptuously, but through and ignorance, inadvertency and weakness, and hoped it would be forgiven.

(k) "in me", Montanus.

When Aaron saw his sister smitten in this way, he said to Moses, "Alas! my lord, I beseech thee, lay not this sin upon us, for we have done foolishly;" i.e., let us not bear its punishment. "Let her (Miriam) not be as the dead thing, on whose coming out of its mother's womb half its flesh is consumed;" i.e., like a still-born child, which comes into the world half decomposed. His reason for making this comparison was, that leprosy produces decomposition in the living body.

And Aaron said unto Moses, Alas, my lord, I beseech thee, lay not the sin upon us, wherein we have done foolishly, and wherein we have sinned.

12:11 Lay not the sin - Let not the guilt and punishment of this sin rest upon us, upon her in this kind, upon me in any other kind, but pray to God for the pardon and removal of it.

11-13. On the humble and penitential submission of Aaron, Moses interceded for both the offenders, especially for Miriam, who was restored; not, however, till she had been made, by her exclusion, a public example [Nu 12:14, 15].

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.
