Liturgy sur L’Exode 14:31
וַיַּ֨רְא יִשְׂרָאֵ֜ל אֶת־הַיָּ֣ד הַגְּדֹלָ֗ה אֲשֶׁ֨ר עָשָׂ֤ה יְהוָה֙ בְּמִצְרַ֔יִם וַיִּֽירְא֥וּ הָעָ֖ם אֶת־יְהוָ֑ה וַיַּֽאֲמִ֙ינוּ֙ בַּֽיהוָ֔ה וּבְמֹשֶׁ֖ה עַבְדּֽוֹ׃ (פ)
Israël reconnut alors la haute puissance que le Seigneur avait déployée sur l’Égypte et le peuple révéra le Seigneur; et ils eurent foi en l’Éternel et en Moïse, son serviteur.
Pesach Haggadah
Rabbi Yose Hagelili says, "From where can you [derive] that the Egyptians were struck with ten plagues in Egypt and struck with fifty plagues at the Sea? In Egypt, what does it state? 'Then the magicians said unto Pharaoh: ‘This is the finger of God' (Exodus 8:15). And at the Sea, what does it state? 'And Israel saw the Lord's great hand that he used upon the Egyptians, and the people feared the Lord; and they believed in the Lord, and in Moshe, His servant' (Exodus 14:31). How many were they struck with with the finger? Ten plagues. You can say from here that in Egypt, they were struck with ten plagues and at the Sea, they were struck with fifty plagues."
