וַיּוֹצִ֣א עַמּ֣וֹ בְשָׂשׂ֑וֹן בְּ֝רִנָּ֗ה אֶת־בְּחִירָֽיו׃
il fit donc sortir son peuple dans l’allégresse, ses élus avec des chants joyeux.
Pirkei DeRabbi Eliezer
Rabbi José said: All that night the Israelites were eating and drinking, rejoicing and taking wine and praising their God with a loud voice, whilst the Egyptians were crying with a bitter soul, because of the plague which came upon them suddenly, as it is said, "And there was a great cry in Egypt; for there was not a house where there was not one dead" (Ex. 12:80).
