if the explanatory clause referred to what was past. If כּי were a causal particle in this case, the meaning could only be, “for every one shall be against his son,” etc. But it is much better to understand it as indicating the object, “that every one may be against his son and against his brother;” i.e., that in the cause of the Lord every one may not spare eve his nearest relative, but deny either son or brother for the Lord's sake (Deu 33:9). “And to give” (or bring), i.e., so that ye may bring, a blessing upon yourselves to-day.” The following, then, is the thought contained in the verse: Provide yourselves to-day with a gift for the Lord, consecrate yourselves to-day for the service of the Lord, by preserving the obedience you have just shown towards Him, by not knowing either son or brother in His service, and thus gain for yourselves a blessing. In the fulfilment of the command of God, with the denial of their own flesh and blood, Moses discerns such a disposition and act as would fit them for the service of the Lord. He therefore points to the blessing which it would bring them, and exhorts them by their election as the peculiar possession of Jehovah (Num 3-4), ), which would be secured to them from this time forward, to persevere in this fidelity to the Lord. “The zeal of the tribe-father burned still in the Levites; but this time it was for the glory of God, and not for their own. Their ancestor had violated both truth and justice by his vengeance upon the Shechemites, from a false regard to blood-relationship, but now his descendants had saved truth, justice, and the covenant by avenging Jehovah upon their own relations” (Kurtz, and Oehler in Herzog's Cycl.), so that the curse which rested upon them (Gen 49:7) could now be turned into a blessing (cf. Deu 33:9).
verses 30-34
After Moses had thus avenged the honour of the Lord upon the sinful nation, he returned the next day to Jehovah as a mediator, who is not a mediator of one (Gal 3:20), that by the force of his intercession he might turn the divine wrath, which threatened destruction, into sparing grace and compassion, and that he might expiate the sin of the nation. He had received no assurance of mercy in reply to his first entreaty (Exo 32:11-13). He therefore announced his intention to the people in these words: “Peradventure I can make an atonement for your sin.” But to the Lord he said (Exo 32:31, Exo 32:32),
