אֲב֘וֹתֵ֤ינוּ בְמִצְרַ֨יִם ׀ לֹא־הִשְׂכִּ֬ילוּ נִפְלְאוֹתֶ֗יךָ לֹ֣א זָ֭כְרוּ אֶת־רֹ֣ב חֲסָדֶ֑יךָ וַיַּמְר֖וּ עַל־יָ֣ם בְּיַם־סֽוּף׃
我們的祖先在埃及時，不領會你的奇事，不記念你豐盛的慈愛，反倒在海邊，就是在紅海那裡，悖逆了。
Rashi
and they were rebellious by the sea They had little faith; they said, “Just as we ascend from here, from this side, the Egyptians also are ascending from another side, and they will come after us,” until the Holy One, blessed be He, hinted to the sea, and it vomited them out onto the dry land. Then (Exod. 14:30) “Israel saw the Egyptians dead on the seashore.” Therefore (ibid. verse 31) “they believed in the Lord,” but in the beginning, they did not believe. I found this.
