1) Why are the ten plagues not all in one parsha? Once they are divided, why specifically seven and three?
2) Ch. 10, v. 1: "Bo" Come Why is BO used here, while in other places Hashem said LEICH?
3) Ch. 10, v. 1: "Bo el Paroh" Come to Paroh We do not find Hashem telling Moshe that the next plague would be that of locust before Moshe told this to Paroh.
4) Ch. 10, v. 1: "V'es leiv avodov" And the hearts of his servants Where do we find that his servants' hearts were hardened?
5) Ch. 10, v. 11: "Lo chein l'chu noh hagvorim v'ivdu es Hashem ki osoh a'tem m'vakshim" - Not so only the men will now go and you shall serve Hashem because that is what you request Paroh seems to be contradicting himself in the same breath. He first says no to sending the children, whom Moshe just included in the previous verse, so how does Paroh say that this is your request?
