Exodus 14:10

And Pharoh saw the idol Zephon (still) preserved, and offered oblations before it. And the children of Israel lifted up their eyes, and, beheld, the Mizraee were pursuing them; and they were sorely afraid, and the children of Israel prayed before the Lord.

AND THEY WERE SORE AFRAID; AND THE CHILDREN OF ISRAEL CRIED OUT UNTO THE ETERNAL. 11. AND THEY SAID UNTO MOSES: ‘BECAUSE WERE THERE NO GRAVES IN EGYPT, HAST THOU TAKEN US TO DIE IN THE WILDERNESS’? It does not appear logical that people who are crying out to G-d to help them, should at the same time protest against the deliverance He performed for them, and say that it would have been better if He had not saved them! The correct interpretation therefore is that there were conflicting groups, and Scripture relates what all of them did. Thus it narrates that one group cried to G-d [for help], and another denied His prophet and did not acknowledge the deliverance done for them. They said it would have been better for them had He not saved them. It is with reference to this group that it is written, They were rebellious at the sea, even at the Red Sea. This is why Scripture here repeats in the same verse the term, the children of Israel, [saying: and ‘the children of Israel’ lifted up their eyes…] and ‘the children of Israel’ cried out unto the Eternal. It thus indicates that it was the better ones among the people that cried out to G-d; the remainder rebelled against His word. This is why Scripture says afterward, And the people feared the Eternal; and they believed in the Eternal, and in His servant Moses. It does not say “and Israel feared the Eternal, and they believed,” but it says instead “the people,” for the term the children of Israel signifies the outstanding ones, while the people is a name for the multitude. Similarly, the verse, And the people murmured,, 15:24. [clearly indicates the usage of the term people in Scripture]. Our Rabbis have also mentioned it: “And the people began to commit harlotry. Wherever it says the people, it is an expression of reproach, and wherever it says Israel, it is one of praise.”
Now the people did not say, “you have taken us away to die in war,” but [they said], hast thou taken us away to die in the wilderness, and again they said, that we should die in the wilderness. This was due to the fact that long before they feared war, they already did not want to go out to the desert lest they die there from hunger and thirst.
It is possible that they said so to Moses upon their going forth from the country while they were still in the land of Egypt, when G-d led them about by the way of the wilderness by …
