(17) When Joshua heard.--Joshua's presence with Moses in the mount has not been indicated since Exodus 24:13. But it would seem that when Moses was summoned up into the cloud (Exodus 24:16) his faithful "minister" remained where he was, waiting for his master. He may have found shelter in some "cleft of the rock;" and the manna may have fallen about him, and sufficed for his sustenance during the forty days and nights of his master's absence.

The noise of the people as they shouted.--"Shouting" was a feature of idolatrous rites (1Kings 18:28; Acts 19:34; Herod. ii. 60, &c.), and was in part a cause, in part a result, of the physical excitement which prevailed during such orgies. Joshua, unsuspicious of the real nature of the shouting, supposed, naturally enough, that the camp was attacked by an enemy, and that the noise was "a noise of war." But Moses, forewarned of the actual state of affairs (Exodus 32:7-8), had probably a shrewd suspicion of the real nature of the sounds. He contented himself, however, with negativing his minister's conjecture.

Verse 17. - When Joshua heard. This abrupt introduction of Joshua, who has not been mentioned for seven entire chapters, is curious. Probably he had considered himself bound, as Moses' minister (Exodus 24:13), to await his return, and had remained in the middle portion of the mount, where he may have fed upon manna, until Moses came down from the top. The noise of the people. It is noted by travellers, that in all the latter part of the descent from Sinai, the plain at its base is shut out from sight; and that sounds would be heard from it a long time before the plain itself would open on the view (Stanley, Sinai and Palestine, p. 44). Sounds, however, which come circuitously, are always indistinct; and it is not surprising that Joshua, knowing nothing of the proceedings in the camp, should have fancied he heard a sound of war.

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.And when Joshua heard the noise of the people, as they shouted,.... Dancing about the calf: when Moses went up into the mount, Joshua went with him, and tarried in a lower part of the mount all the forty days until he returned, see Exodus 24:13 though not so low as the bottom of the mount where the people were, nor so near it as to know what they did there, for of their affairs he seems to be entirely ignorant; nor so high as where Moses was, or, however, not in the cloud where he conversed with God, for of what passed between them he had no knowledge, until declared by Moses:

he said unto Moses, there is a noise of war in the camp; such a noise as soldiers make in an onset for battle; he supposed that some enemy was come upon and had attacked the people, and that this noise was the noise of the enemy, or of the Israelites, or both, just beginning the battle; or on the finishing of it on the account of victory on one side or the other; and as he was the general of the army, it must give him a concern that he should be absent at such a time.
