(29) But the Israelites had marched through the sea on dry ground, the waters forming a wall for them on their right and on their left. (30) Thus the LORD delivered Israel that day from the Egyptians. Israel saw the Egyptians dead on the shore of the sea. (31) And when Israel saw the wondrous power which the LORD had wielded against the Egyptians, the people feared the LORD; they had faith in the LORD and His servant Moses. (1) Then Moses and the Israelites sang this song to the LORD. They said:
I will sing to the LORD, for He has triumphed gloriously;
Horse and driver He has hurled into the sea.

Who is like You, O LORD, among the celestials;
Who is like You, majestic in holiness,
Awesome in splendor, working wonders!

Now when Pharaoh let the people go, God did not lead them by way of the land of the Philistines, although it was nearer; for God said, “The people may have a change of heart when they see war, and return to Egypt.”

Rabbi Reuben said: The entire body follows the head, and when the shepherd goes astray the sheep go astray after him, as it is said, "For the sins of Jeroboam which he sinned, and wherewith he made Israel to sin" (1 Kings 15:30). When the shepherd is good, all follow after him. Moses began to sing, and to utter praises before the Holy One, blessed be He, and all Israel followed him, as it is said, "Then sang Moses and the children of Israel" (Ex. 15:1). Miriam began to sing and to utter praises, before the Holy One, blessed be He, and all the women followed her, as it is said, "And Miriam the prophetess, the sister of Aaron, took a timbrel… and all the women went out after her" (Ex. 15:20). Whence did they have timbrels and chorus in the wilderness? But the righteous always know and conciliate (God), and are assured that the Omnipresent, blessed be He, performs for them miracles and mighty deeds. Before (the time of) their departure from Egypt they prepared for themselves timbrels and chorus.

And similarly, Rabbi Yoḥanan said: What is the meaning of that which is written: “And the one came not near the other all the night” (Exodus 14:20)? The ministering angels wanted to sing their song, for the angels would sing songs to each other, as it states: “And they called out to each other and said” (Isaiah 6:3), but the Holy One, Blessed be He, said: The work of My hands, the Egyptians, are drowning at sea, and you wish to say songs? This indicates that God does not rejoice over the downfall of the wicked.

Then Moses caused Israel to set out from the Sea of Reeds. They went on into the wilderness of Shur; they traveled three days in the wilderness and found no water.
