אֲב֘וֹתֵ֤ינוּ בְמִצְרַ֨יִם ׀ לֹא־הִשְׂכִּ֬ילוּ נִפְלְאוֹתֶ֗יךָ לֹ֣א זָ֭כְרוּ אֶת־רֹ֣ב חֲסָדֶ֑יךָ וַיַּמְר֖וּ עַל־יָ֣ם בְּיַם־סֽוּף׃
Ang aming mga ninuno sa Egipto ay hindi nag-unawa sa Iyong mga kababalaghan; hindi nila inalaala ang dami ng Iyong kagandahang-loob, at sila ay naghimagsik sa may dagat, sa Dagat na Pula.

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.
