Comentário sobre Deuteronômio 32:48

וידבר ה' אל משה בעצם היום הזה AND THE LORD SPAKE TO MOSES THAT SELF SAME DAY — In three places in Scripture the expression בעצם היום הזה is used. It states in the narrative of Noah (Genesis 7:12) בעצם היום הזה entered Noah … [into the ark]” — which means in the glare of full daylight. Because his contemporaries said: By this and by that we swear; (cf. Note 2 on Deuteronomy 1:1): If we notice him about to do so we will not let him enter the ark, and not only that, but we will take axes and hatchets and we will split the ark in pieces. Thereupon the Holy One, blessed be He, said, “See, I will let him enter at midday and anyone who has power to prevent it, let him come and prevent it!” Of Egypt, too, it states, (Exodus All. 11) “The selfsame day the Lord did bring [the children of Israel out of the land of Egypt]”: because the Egyptians said: By this and by that! If we notice them about to do so, we will not let them leave, and not only that, but we will take swords and other weapons and will kill them. Thereupon said the Holy One, blessed be He, “See, I will bring them forth in the middle of the day, and anyone who has power to prevent it, let him come and prevent it!” Here, too, regarding Moses’ death, it states בעצם היום הזה, because the children of Israel said, By this and by that! If we notice him about to ascend the mountain, we will not let him do so, — the man who brought us out of Egypt, and divided the Red Sea for us, and brought the Manna down for us, and brought a flight of quails for us, and made the “well” rise, and gave us the Torah: we will not permit him to go!” Thereupon the Holy One, blessed be He, said, “Behold, I will bring him unto his resting place in the middle of the day, etc.” (Sifrei Devarim 337; cf. Rashi on Genesis 17:23).

At the very height of that day. The day of death is called a person’s sunset, but when Moshe died, “His appearance was not dulled and his freshness did not fade.” Therefore it was as if he was still in the middle of his life, and at the height of his day.

בעצם היום הזה לאמור. "on that very day, saying." Moses was to tell the people that he would ascend the mountain in order to die. This corresponds to what Sifri explains on the word בעצם that on the three occasions when this word appears it reflects G'd's determination not to be interfered with. In this instance the Israelites had threatened to physically prevent Moses from ascending the mountain to die there.
