That is what Rabbi Eleazar said: What means the text: And when they shall say unto you, Seek unto them that have familiar spirits and unto the wizards, that chirp and that mutter?

They saw that Israel's saviour would be punished through water; so they arose and decreed, Every son that is born ye shall cast into the river. [footnote states: "Ex. I, 22."] After they had thrown Moses [into the water], they said: 'We do not see that sign any longer'; [footnote states: "Indicating that the peril to Pharaoh was averted by this action."] they thereupon rescinded their decree. But they knew not that he was to be punished through the water of Meribah. [footnote states: "And that this was the meaning of the sign they had seen."] [footnote states: "Num. XX. 13."] That is what Rabbi Hama ben Hanina said: What means the text: These are the waters of Meribah, because they strove? [footnote states: "Num. XX. 13."] These are [the waters] about which Pharaoh's magicians saw and erred; and concerning this Moses said: Six hundred thousand footmen etc. [footnote states: "Ibid. XI, 21. Footmen is in Hebrew ragli which can also mean 'for my sake'."] Moses said to Israel, 'On my account were all of you delivered [from drowning by the edict of Pharaoh]'.
