Midrash BeChiddush
14. Further: “So that God caused Him to move forward…” (Ex. 14:25) refers to wicked Samael as mentioned. When he saw that his authority had been removed (from the Egyptians), he no longer wanted to go with them and he was forced to move forward with them with great difficulty when he saw the judgments that was brought upon their celestial prince. This made him reason with a Kal Vachomer199 A Fortiori argument: A kal vachomer, literally "lenient and strict" derives one law from another through the following logic: If a case that is generally strict has a particular leniency, a case that is generally lenient will certainly have that leniency. The argument can also work in reverse, and also in areas where lenient or strict might not be precisely applicable. (Wikipedia) The kal vachomer appears to be if, Sama’el the celestial prince of Esau failed to help the Egyptians when own prince failed then surely he would not be able to assist his own nation of Edom. Edom is often associated in Midrash with Rome and With Christendom. for the future: For him, too, would come the cup (of retribution) as is written, “I will show him wondrous deeds as in the days when You went forth from the land of Egypt.” (Mic. 7:15) This caused great pain to the Egyptians who put their trust in Samael, for the nation could not be victorious except through the strength of the celestial prince of Esau, who is none other than Samael. “and I will break your proud glory…. so that your strength shall be spent to no purpose,” (Lev. 26:20)
