I know not the Lord - Either Pharaoh had not heard of Yahweh, or he did not recognize Him as a God.

Who is the Lord - Who is Jehovah, that I should obey his voice? What claims has he on me? I am under no obligation to him. Pharaoh spoke here under the common persuasion that every place and people had a tutelary deity, and he supposed that this Jehovah might be the tutelary deity of the Israelites, to whom he, as an Egyptian, could be under no kind of obligation. It is not judicious to bring this question as a proof that Pharaoh was an atheist: of this the text affords no evidence.

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.

And Pharaoh said, Who is the LORD, that I should obey his voice to let Israel go? I know not the LORD, neither will I let Israel go.

5:2 Who is the Lord that I should obey his voice? - Being summoned to surrender, he thus hangs out the flag of defiance. Who is Jehovah? I neither know him nor care for him; neither value nor fear him. It is a hard name that he never heard of before, but he resolves it shall be no bugbear to him. Israel was now a despised, oppressed people, and by the character they bore he makes his estimate of their God, and concludes that he made no better figure among the gods, than his people did among the nations.

2. And Pharaoh said, Who is the Lord-rather "Jehovah." Lord was a common name applied to objects of worship; but Jehovah was a name he had never heard of. Pharaoh estimated the character and power of this God by the abject and miserable condition of the worshippers and concluded that He held as low a rank among the gods as His people did in the nation. To demonstrate the supremacy of the true God over all the gods of Egypt, was the design of the plagues.

I know not the Lord, neither will I let Israel go-As his honor and interest were both involved he determined to crush this attempt, and in a tone of insolence, or perhaps profanity, rejected the request for the release of the Hebrew slaves.

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.
