The use of "you" in Exodus 33

When we come to Exodus 33:12-16, all efforts at atonement for the sin of the golden calf have failed in renewing God's covenant with His people. Here Moses seems truly at a loss: he has burned the calf and made the people consume its ashes from the water; he has had the sons of Levi put 3,000 men to the sword; he has tried to atone for their sins by offering his own life; the Lord has sent a plague; the Lord has made them rid themselves of ornaments; yet even in this last instance it is obvious that the question remains even now with Moses in this encounter if Israel is restored by God to the covenant He had made with Abraham, Isaac, Jacob, and Joseph. The last word on the subject was God declaring, “if for a single moment I should go up among you [Israel], I would consume you. So now take off your ornaments, that I may know what to do with you,” (Exodus 33:5). So, we have Moses in the tent interceding for the people, and we read: “And [the Lord] said, ‘My presence will go with you, and I will give you rest,” (Exodus 33:14). It is hard to see if perhaps there is ambiguity in “you” here, whether the Lord is speaking uniquely of Moses, or of Moses and the people. It is in the second person masculine singular, but that is also the case elsewhere when it is obvious that all Israel is understood. For example, where God says “for you are a stiff-necked people,” (Exodus 33:3), He is addressing them in second person masculine singular. Yet, when God repeats the phrase as direct speech that Moses is to convey to the people, “Say to the people of Israel, ‘You are a stiff-necked people,’” (Exodus 33:5), He uses the second person masculine plural. Then, in the same direct speech, referring still to the people Israel, God says “among you,” “consume you,” “your ornaments,” “with you,” all in the singular. Yet, it seems to be something of the point that Moses is turning on as he intercedes for the people, where he adds that, while he has found favor with God, “Consider too that this nation is your people,” (Exodus 33:13), and again, “I and your people,” (v 16). Does Moses remain unsure of the standing of Israel and God's covenant with them in part because God is addressing Moses uniquely? Sorry for the length.
