出埃及記 14:16 註釋：Rashbam, Sforno, Rabbeinu Bahya & Chizkuni

ובקעהו, the letter ע with the vowel tzeyreh converts the intransitive mode, as does the tzeyreh in the word שמענו in Genesis 23,6; on the other hand, in the construction זכרני, zochreyni, based on the root זכר, the first letter of the root has the full vowel kametz. (Psalms 106,4)

הרם את מטך, in the direction of the east wind so that it will cause the sea bed to dry out.

ואתה הרם את מטך ונטה את ידך, “as for you, raise your staff and incline your hand.” We must not understand this verse as an instruction to Moses to raise his staff above the sea. After all, the Torah does not report Moses as raising his staff over the sea. He only raised his hand over the sea (verse 21). The meaning of the words “raise your staff” is that Moses was to divest himself of the staff. You find confirmation of this in Shemot Rabbah 21,9 where the Midrash quotes the Egyptians as saying that Moses’ entire strength lay in his staff, that he was unable to do anything without it. There were also some Israelites who did not believe that Moses would be able to perform such a miracle without the aid of his staff. G’d therefore told him to get rid of the staff and to perform the miracle with his hand. This is why we read subsequently that the people had faith in G’d and His servant Moses, seeing that he had been able to perform such a miracle merely with his hand (verse 31). Whereas previously the Torah had stated that the people did have faith in Moses (4,31), this faith had been shaken in the interval. It was therefore necessary for the Torah to write in connection with the splitting of the Sea that their faith in Moses had been completely restored.
