Exodus 15:22

ויסע משה AND MOSES CAUSED [ISRAEL] TO JOURNEY — He made them journey against their own will, because the Egyptians had adorned their horses with ornaments of gold and silver and with precious stones, and the Israelites were finding these in the sea. Greater, indeed, was the booty they obtained at the Red Sea then the booty they had brought out of Egypt — as it is said (Song 1:11) “Circlets of gold (the booty of the Sea) will we make thee together with the studs of silver” (which we brought forth from Egypt) (Mekhilta). On this account he was compelled to make them journey on against their will.

וַיַּסַּ֨ע מֹשֶׁ֤ה אֶת־יִשְׂרָאֵל֙ מִיַּם־ס֔וּף וַיֵּצְא֖וּ אֶל־מִדְבַּר־שׁ֑וּר וַיֵּלְכ֧וּ שְׁלֹֽשֶׁת־יָמִ֛ים בַּמִּדְבָּ֖ר וְלֹא־מָ֥צְאוּ מָֽיִם׃

So Moshe brought Yisra᾽el from the Sea of Suf, and they went out to the wilderness of Shur; and they marched three days in the wilderness, and found no water.
