What does Exodus 10:10 mean?
This remark may be sarcastic, but it is certainly a refusal. Pharaoh is attempting to negotiate out of the impending plague of locusts (Exodus 10:3–7). He has suggested that some Hebrew slaves be given leave to worship (Exodus 10:8). Moses has made it clear that every person, animal, and resource which belongs to Israel will be leaving. There is no room for negotiation there.Pharaoh is sneering at the idea that he would voluntarily release the Israeli children. Translators differ slightly in how they interpret his words. He may be sarcastically using the name Yahweh, printed in English as "Lord." He may be saying that Moses and Aaron would need divine protection if such a thing happened. He may be ironically saying that it would be a genuinely great miracle if he agreed with Moses.
The reference to evil can also be interpreted in different ways. This may be Pharaoh's attempt to blame Moses and Aaron for his own actions. It might be a threat: a warning that he may choose to retaliate as he did before (Exodus 5:9, 17–19). Either way, it emphasizes his refusal to release all God's people.
