(2) Who is the Lord?--Heb., Who is Jehovah? If Jehovah was a name, the use of which had been laid aside, as would seem to have been the case by the later chapters of Genesis, and which was revived by the scene at the burning bush, Pharaoh may very probably not have heard of it.

That I should obey his voice.--The king means to say, that, whoever Jehovah is, He can have no authority over him, as He is not one of his gods. The Egyptians were accustomed to the idea of local gods, and quite expected every nation to have a deity or several deities of its own; but they regarded the power of each as circumscribed, certainly not extending beyond the race or nation to which the god belonged.

Verse 2. - And Pharaoh said, Who is the Lord? Rather, "Who is Jehovah?" Either Pharaoh is actually ignorant, or he pretends to be. The former is possible, since Jehovah was a name but little employed, until the return of Moses to Egypt. The latter, however, is more probable. That I should obey his voice. Why am I to obey his voice? What is your Jehovah to me? What authority has he over me? He is, at best, your god, not mine. I know not Jehovah. I acknowledge him not. He is not within the range of my Pantheon. Neither will I let Israel go, i.e. "nor even, if he were, would I consent to such a request as this from him." The Pharaohs assumed to be themselves gods, on a par with the national gods, and not bound to obey them.

5:1-9 God will own his people, though poor and despised, and will find a time to plead their cause. Pharaoh treated all he had heard with contempt. He had no knowledge of Jehovah, no fear of him, no love to him, and therefore refused to obey him. Thus Pharaoh's pride, ambition, covetousness, and political knowledge, hardened him to his own destruction. What Moses and Aaron ask is very reasonable, only to go three days' journey into the desert, and that on a good errand. We will sacrifice unto the Lord our God. Pharaoh was very unreasonable, in saying that the people were idle, and therefore talked of going to sacrifice. He thus misrepresents them, that he might have a pretence to add to their burdens. To this day we find many who are more disposed to find fault with their neighbours, for spending in the service of God a few hours spared from their wordly business, than to blame others, who give twice the time to sinful pleasures. Pharaoh's command was barbarous. Moses and Aaron themselves must get to the burdens. Persecutors take pleasure in putting contempt and hardship upon ministers. The usual tale of bricks must be made, without the usual allowance of straw to mix with the clay. Thus more work was to be laid upon the men, which, if they performed, they would be broken with labour; and if not, they would be punished.And Pharaoh said, who is the Lord,.... Jehovah, they made mention of, which, whether he took it for the name of a deity, or of a king, whose ambassadors they declared themselves to be, was a name he had never heard of before; and this being expressed and pronounced, shows that this name is not ineffable, or unlawful to be pronounced, as say the Jews:

that I should obey his voice, to let Israel go? he knew of no superior monarch to him, whose orders he was obliged to obey in any respect, and particularly in this, the dismission of the people of Israel out of his land, though it was but for a short time:

I know not the Lord; who this Jehovah is, that made this demand, and required Israel's dismission. The Targum of Jonathan paraphrases it,"I have not found the name of Jehovah written in the book of angels, I am not afraid of him.''An Egyptian book, in which, the paraphrast supposes, were written the names of gods and of angels; and no such name being there, he was the more bold and insolent:

neither will I let Israel go; determining he would pay no regard to such an unknown Deity, or King, be he who he would.
