Go in, and speak to Pharao king of Egypt, that he let the children of Israel go out of his land.

Go in, speak to Pharaoh, king of Egypt, that he let the children of Israel depart from his land.

'Go in, speak unto Pharaoh king of Egypt, and he doth send the sons of Israel out of his land;

Go in and say to Pharaoh, king of Egypt, that he is to let the children of Israel go out of his land.

"Enter and speak to Pharaoh, king of Egypt, so that he may release the sons of Israel from his land."

Ingredere et Ioquere ad Pharaonem regem Aegypti, ut dimittat filios Israel e terra sua.

Go out of his land - Moses is now bidden to demand not a permission for a three days' journey (Exodus 3:18 note), which might be within the boundaries of Egypt, but for departure from the land.

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.

That he let the children of Israel go - God repeats his precepts, before he begins his punishments. Those that have oft been called in vain to leave their sins, yet must be called again, and again.
