57. When Yisrael left Egypt, they did not know the Holy One, blessed be He. When Moses came to them, he taught them this first precept, as it is written, "And you shall know that I am Hashem your Elohim, who brings you out..." Were it not for this commandment, Yisrael would not be faithful TO HASHEM, EVEN AFTER all these miracles and mighty acts that THE HOLY ONE, BLESSED BE HE, performed for them in Egypt. After they knew this commandment in general, miracles and mighty deeds were performed for them, FOR THEY WERE ALREADY CERTAIN THAT THEY WOULD BELIEVE IN HASHEM THROUGH THEM, AS IT IS WRITTEN, "AND YISRAEL SAW...AND BELIEVED IN HASHEM, AND IN MOSES HIS SERVANT" (SHEMOT 14:31).
