1 sn The clause is a rhetorical question. Pharaoh is not asking them why they do this, but rather is accusing them of doing it. He suspects their request is an attempt to get people time away from their labor. In Pharaoh’s opinion, Moses and Aaron were “removing the restraint” (פָּרַע, para’) of the people in an effort to give them rest. Ironically, under the Law the people would be expected to cease their labor when they went to appear before God. He would give them the rest that Pharaoh refused to give. It should be noted also that it was not Israel who doubted that Yahweh had sent Moses, as Moses had feared – but rather Pharaoh.
2 tn Heb “And Pharaoh said.” This is not the kind of thing that Pharaoh is likely to have said to Moses, and so it probably is what he thought or reasoned within himself. Other passages (like Exod 2:14; 3:3) show that the verb “said” can do this. (See U. Cassuto, Exodus, 67.)
