Exodus 6:11

Go in
Into Pharaoh's palace, and into his presence, to whom access seems not to be very difficult; and perhaps access to princes was not attended with so much ceremony then as it now is:

speak unto Pharaoh king of Egypt;
though a king, and a king of so large a country as Egypt, yet do not be afraid to speak to him; speak to him plainly and boldly, not in a supplicatory, but in an authoritative way, in the name of the King of kings:

that he let the children of Israel go out of his land;
this demand had been made before, but was rejected with an haughty air, and now it is repeated, before the Lord proceeds to punish him for his disobedience, that his judgments upon him might appear more manifestly to be just and right.
