(Exodus 13:18) "And G–d led the people circuitously by way of the desert to the Red Sea": in order to perform miracles and mighty acts with the manna and the quail and the well. R. Eliezer says: "way"—in order to weary them, viz. (Psalms 102:24) "He drained my strength on the way; He shortened my days." "the desert"—in order to purify them, viz. (Devarim 8:15) "Who led you through the great and awesome desert." "the Red Sea"—in order to try them, viz. (Psalms 106:7) "Our fathers in Egypt did not absorb Your wonders. They did not remember the abundance of Your lovingkindness, and they rebelled at the sea, at the Red Sea." R. Yehoshua says: "way"—in order to give them the Torah, of which it is written (Devarim 5:30) "In all the way that the L–rd your G–d has commanded you shall you go," and (Mishlei 6:23) "For a mitzvah is a lamp, and Torah is light, and the way of life." "the desert"—in order to feed them the manna, viz. (Devarim 8:16) "who fed you manna in the desert, etc." "the Red Sea"—in order to perform for them miracles and wonders, as it is written (Psalms 106:21-22) "They forgot the G–d who saved them, who wrought great deeds in Egypt, wonders in the land of Cham, awesome acts at the Red Sea," and (Ibid. 9) "And He rebuked the Red Sea and it dried up, and He led them through the depths as through a desert."
