The tables were written on both their sides - If we take this literally, it was certainly a very unusual thing; for in ancient times the two sides of the same substance were never written over. However, some rabbins suppose that by the writing on both sides is meant the letters were cut through the tables, so that they might be read on both sides, though on one side they would appear reversed. Supposing this to be correct, if the letters were the same with those called Hebrew now in common use, the ס samech, which occurs twice, and the final ם mem which occurs twenty-three times in the ten commandments, both of these being close letters, could not be cut through on both sides without falling out, unless, as some of the Jews have imagined, they were held in by miracle; but if this ancient character were the same with the Samaritan, this through cutting might have been quite practicable, as there is not one close letter in the whole Samaritan alphabet. On this transaction there are the three following opinions:

1. We may conceive the tables of stone to have been thin slabs or a kind of slate, and the writing on the back side to have been a continuation of that on the front, the first not being sufficient to contain the whole.

2. Or the writing on the back side was probably the precepts that accompanied the ten commandments; the latter were written by the Lord, the former by Moses; see Clarke's note on Exodus 34:1. See Clarke's note on Exodus 34:27.

3. Or the same words were written on both sides, so that when held up, two parties might read at the same time.

And Moses turned, and went down from the mount,.... He turned himself from God, with whom he had been conversing forty days; his back was to the ascent of the mount, and he turned himself in order to go down; or "he looked" (g), as a man considers what is to be done, as Aben Ezra observes, and he saw that he was obliged to go down in haste:

and the two tables of the testimony were in his hand; or hands, as in Exodus 32:19 for they were, perhaps, as much as he could carry in both hands, being of stone, as in Exodus 31:18 on which was written the law, the "testimony" of the will of God with respect to what was to be done or not done:

the letters were written on both their sides, on the one side and on the other were they written; some think that the engraving of the letters was such, that it went through the stones, and in a miraculous manner the letters and lines were in a regular order, and might be read on the other sides; to which Jarchi seems to incline, saying, the letters might be read, and it was a work of wonders; others think that the letters were written both within and without, like Ezekiel's book of woes; that the same that was within side was written without, that so, when held up, they might be read by those that stood before and those that stood behind; but rather so it was that the whole was written within, some of the commands on the right, and some on the left, and so the tables might be clapped together as a book is folded.

When Moses departed from God with the two tables of the law in his hand (see at Exodus 31:18), and came to Joshua on the mountain (see at ch. Joshua 24:13), the latter heard the shouting of the people (lit., the voice of the people in its noise, רעה for רעו, from רע noise, tumult), and took it to be the noise of war; but Moses said (Exodus 32:18), "It is not the sound of the answering of power, nor the sound of the answering of weakness," i.e., they are not such sounds as you hear in the heat of battle from the strong (the conquerors) and the weak (the conquered); "the sound of antiphonal songs I hear." (ענּת is to be understood, both here and in Psalm 88:1, in the same sense as in Exodus 15:21.)

And Moses turned, and went down from the mount, and the two tables of the testimony were in his hand: the tables were written on both their sides; on the one side and on the other were they written.

32:15 On both their sides - Some on one table and some on the other, so that they were folded together like a book, to be deposited in the ark.

15-18. Moses turned, and went down from the mount-The plain, Er-Raheh, is not visible from the top of Jebel Musa, nor can the mount be descended on the side towards that valley; hence Moses and his companion, who on duty had patiently waited his return in the hollow of the mountain's brow, heard the shouting some time before they actually saw the camp.

32:15-20 What a change it is, to come down from the mount of communion with God, to converse with a wicked world. In God we see nothing but what is pure and pleasing; in the world nothing but what is sinful and provoking. That it might appear an idol is nothing in the world, Moses ground the calf to dust. Mixing this powder with their drink, signified that the backslider in heart should be filled with his own ways.
