Liturgy do Psalmów 78:49

Rabbi Eliezer says, "From where [can you derive] that every plague that the Holy One, blessed be He, brought upon the Egyptians in Egypt was [composed] of four plagues? As it is stated (Psalms 78:49): 'He sent upon them the fierceness of His anger, wrath, and fury, and trouble, a sending of messengers of evil.' 'Wrath' [corresponds to] one; 'and fury' [brings it to] two; 'and trouble' [brings it to] three; 'a sending of messengers of evil' [brings it to] four. You can say from here that in Egypt, they were struck with forty plagues and at the Sea, they were struck with two hundred plagues."

Rabbi Akiva says, says, "From where [can you derive] that every plague that the Holy One, blessed be He, brought upon the Egyptians in Egypt was [composed] of five plagues? As it is stated (Psalms 78:49): 'He sent upon them the fierceness of His anger, wrath, and fury, and trouble, a sending of messengers of evil.' 'The fierceness of His anger' [corresponds to] one; 'wrath' [brings it to] two; 'and fury' [brings it to] three; 'and trouble' [brings it to] four; 'a sending of messengers of evil' [brings it to] five. You can say from here that in Egypt, they were struck with fifty plagues and at the Sea, they were struck with two hundred and fifty plagues."
