Deuteronomy 9:25

25.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.
