Midrash sobre Exodo 14:21

(Cant. 2:12:) THE BLOSSOMS HAVE APPEARED IN THE LAND. These are the redeemers (i.e., Moses and Aaron).³²Cant. R. 2:12:1. (Ibid., cont.:) THE TIME OF PRUNING (rt.: ZMR) HAS ARRIVED, <i.e.,> The time for the foreskin to be pruned (rt.: ZMR) has arrived, as stated (in Exod. 15:2): THE LORD IS MY STRENGTH AND MY CIRCUMCISION (rt.: ZMR).³³So has the midrash understood the text. More common translations would be either THE LORD IS MY STRENGTH AND MY MIGHT OR THE LORD IS MY STRENGTH AND MY SONG. Cf. PR 15:11, which finds the concept of pruning in the idea of the sea dividing (Exod. 14:21). Cf. also PR 15:12, which alludes to the Canaanites being cut down and the land being divided (Numb. 26:53). The time for Torah to be given has arrived, since there is written concerning it (in Ps. 119:54): YOUR LAWS HAVE BEEN MY SONGS (rt.: ZMR).³⁴Cf. Sot. 35a. (Cant. 2:12, cont.:) AND THE VOICE OF THE TURTLEDOVE IS HEARD IN OUR LAND. R. Johanan said: This VOICE OF THE TURTLEDOVE (TWR) refers to Moses,³⁵Cf. PR 15:11, which adds here that Moses led Israel through the turnings (TYYRI) of their wanderings. Cf. also PRK 5:9. since it is stated (in Exod. 11:4): THEN MOSES SAID: THUS SAYS THE LORD: ABOUT MIDNIGHT <I SHALL GO FORTH INTO THE MIDST OF EGYPT>…. (Cant. 2:13:) AND THE FIG TREE SHEDS³⁶Heb.: Hanetah. Although this rare verb can mean “enbalm” (as in Gen. 50:2, 26), here the biblical context suggests a translation such as “give form to,” “put forth,” “fill with juice,” or “ripen.” The midrash, however, understands the word in a more negative sense such as “overripen” or “shed.” ITS GREEN FIGS. These are the wicked Israelites who died during the three days of darkness. (Ibid., cont.:) AND THE BLOOMING VINES GIVE OFF AN AROMA. These are the mediocre ones who have been accepted through <the aroma of> repentance. The Holy One said to them: Why are you sitting <there>? (In the words of Cant. 2:10) ARISE. The wicked are dead and the mediocre ones have repented. ARISE, (for in the words of Exod. 12:2): In THIS MONTH you are being redeemed.

“The blossoms have appeared in the land, the time of the nightingale has arrived, and the sound of the turtledove is heard in our land” (Song of Songs 2:12).
“The blossoms [hanitzanim] have appeared in the land,” the administrators [hanatzoḥot] have appeared in the land; these are Moses and Aaron, as it is stated: “The Lord said to Moses and Aaron in the land of Egypt, saying” (Exodus 12:1).¹¹⁰This is the month of redemption and they would be the leaders who facilitate that redemption.
“The time of the nightingale [hazamir] has arrived,” the time for Israel to be redeemed has arrived, the time for the foreskin to be cut off [shetizamer] has arrived, the time for Egypt to be cut off has arrived, the time for their idol worship to be uprooted has arrived, as it is stated: “And I will administer punishments against all the gods of Egypt” (Exodus 12:12). The time for the sea to have its water split has arrived, as it is stated: “The water split” (Exodus 14:21). The time for song has arrived, as it is stated: “Then Moses…sang” (Exodus 15:1). Rabbi Tanḥuma said: The time to compose paeans to the Holy One blessed be He has arrived, as it is stated: “The Lord is my strength and my song [vezimrat ya]” (Exodus 15:2); paeans to the Lord [zemirot ya]. Rabbi Beivai said: “Your statutes were paeans to me” (Psalms 119:54). ”The sound of the turtledove [hator] is heard in our land,” Rabbi Yoḥanan said: The voice of a good explorer [tayar] was heard in our land; this is Moses, at the time that he said: “Moses said: So said the Lord: At about midnight” (Exodus 11:4).

..."And the waters were a wall for them" Made them as a type of wall. "On their right and on their left" On their right due to the merit of the Torah that they would in the future receive through the right, as it is said "From His right, a fiery law to them" (Deut. 33:2). And on their left: this is prayer.
