Thus I fell down before the LORD forty days and forty nights, as I fell down at the first; because the LORD had said he would destroy you.

And I lay prostrate before the Lord forty days and nights, in which I humbly besought him, that he would not destroy you as he had threatened:

And I throw myself before Jehovah, the forty days and the forty nights, as I had thrown myself, for Jehovah hath said, to destroy you;

So I went down on my face in prayer before the Lord for forty days and forty nights as I did at first; because the Lord had said that he would put an end to you.

And so, I lay prostrate before the Lord for forty days and nights, as I humbly begged him, lest he destroy you, just as he had threatened to do.

Et procidi coram Jehova quadraginta diebus et quadraginta noctibus, quibus procidi: quia dixerat Jehova se perditurum vos.

Thus I fell down before the Lord forty days Again the narrative is blended together; for it is certain that this prayer was offered before he remained fasting in the mount during the second forty days. But inasmuch as then also, being still in anxiety, he continued the same prayers, it is not to be wondered at that he should include in the forty days' fast whatever had been done before. For there is no absurdity in supposing that after having obtained the safety of the people, for which he had petitioned, he should still be in trepidation. Moreover, that this fast was posterior to the prayer which he mentions at the same time, may be inferred from the beginning of the next chapter, where he records that the second tables were given to him, but says not a word of the fast. I have stated why he so often repeats his allusion to the forty days, viz., because it would not have been sufficient merely to intercede, unless this reconciliation had followed, which he obtained when he received the new covenant. The rest I have already expounded.

Thus I fell down before the LORD (o) forty days and forty nights, as I fell down [at the first]; because the LORD had said he would destroy you.
(o) By which is signified that God requires earnest continuance in prayer.

Thus I fell down before the Lord forty days and forty nights, as I fell down at the first,.... Which Jarchi says are the selfsame said above, Deuteronomy 9:18, but doubled or repeated, because of the order of his prayer. The words "at the first" are not in the text; and, as before observed, we do not read that Moses fell down at the first forty days he was in the mount, unless it can be thought he did, Exodus 32:11, wherefore this falling down seems to be as he fell down at the second forty days; and so this was a third forty days, according to the Jewish writers, and of which opinion were Dr. Lightfoot and others; See Gill on Exodus 34:28,
because the Lord had said he would destroy you; threatened them with destruction, and seemed as if it was his intention to destroy them; nay, even after Moses's first prayer, though he bid him go and lead the people on, yet he declared that he would visit their sin upon them, Exodus 32:34.

Thus I fell down before the Lord forty days and forty nights, as I fell down at the first--After the enumeration of various acts of rebellion, he had mentioned the outbreak at Kadesh-barnea, which, on a superficial reading of this verse, would seem to have led Moses to a third and protracted season of humiliation. But on a comparison of this passage with Numbers 14:5, the subject and language of this prayer show that only the second act of intercession (Deuteronomy 9:18) is now described in fuller detail.

After vindicating in this way the thought expressed in Deuteronomy 9:7, by enumerating the principal rebellions of the people against their God, Moses returns in Deuteronomy 9:25. to the apostasy at Sinai, for the purpose of showing still further how Israel had no righteousness or ground for boasting before God, and owed its preservation, with all the saving blessings of the covenant, solely to the mercy of God and His covenant faithfulness. To this end he repeats in Deuteronomy 9:26-29 the essential points in his intercession for the people after their sin at Sinai, and then proceeds to explain still further, in Deuteronomy 10:1-11, how the Lord had not only renewed the tables of the covenant in consequence of this intercession (Deuteronomy 10:1-5), but had also established the gracious institution of the priesthood for the time to come by appointing Eleazar in Aaron's stead as soon as his father died, and setting apart the tribe of Levi to carry the ark of the covenant and attend to the holy service, and had commanded them to continue their march to Canaan, and take possession of the land promised to the fathers (Deuteronomy 10:6-11). With the words "thus I fell down," in Deuteronomy 9:25, Moses returns to the intercession already briefly mentioned in Deuteronomy 9:18, and recalls to the recollection of the people the essential features of his plea at the time. For the words "the forty days and nights that I fell down," see at Deuteronomy 1:46. The substance of the intercession in Deuteronomy 9:26-29 is essentially the same as that in Exodus 32:11-13; but given with such freedom as any other than Moses would hardly have allowed himself (Schultz), and in such a manner as to bring it into the most obvious relation to the words of God in Deuteronomy 9:12, Deuteronomy 9:13. אל־תּשׁחת, "Destroy not Thy people and Thine inheritance," says Moses, with reference to the words of the Lord to him: "thy people have corrupted themselves" (Deuteronomy 9:12). Israel was not Moses' nation, but the nation and inheritance of Jehovah; it was not Moses, but Jehovah, who had brought it out of Egypt. True, the people were stiffnecked (cf. Deuteronomy 9:13); but let the Lord remember the fathers, the oath given to Abraham, which is expressly mentioned in Exodus 32:13 (see at Deuteronomy 7:8), and not turn to the stiffneckedness of the people (קשׁי equivalent to ערף קשׁה, Deuteronomy 9:13 and Deuteronomy 9:6), and to their wickedness and sin (i.e., not regard them and punish them). The honour of the Lord before the nations was concerned in this (Deuteronomy 9:28). The land whence Israel came out ("the land" = the people of the land, as in Genesis 10:25, etc., viz., the Egyptians: the word is construed as a collective with a plural verb) must not have occasion to say, that Jehovah had not led His people into the promised land from incapacity or hatred. יכלת מבּלי recalls Numbers 14:16. Just as "inability" would be opposed to the nature of the absolute God, so "hatred" would be opposed to the choice of Israel as the inheritance of Jehovah, which He had brought out of Egypt by His divine and almighty power (cf. Exodus 6:6).

I fell down forty days - The same as were mentioned before, Deuteronomy 9:18, as appears by comparing this with Exodus, where this history is more fully related, and where this is said to be done twice only.
