There are a remarkable number of parallels between this series of judgments and the ten plagues in Exodus. For example, trumpets are associated with the theophany at Sinai (Exod 19:13-19; 20:18). The first trumpet judgment is similar to Exodus 9:13-25, hail and fire fell upon the Egyptians. The third trumpet resembles the plague of the freshwater in Exodus 7:20, except that there the waters turned to blood. The locust in Rev 9:3 is an apocalyptic version of the eighth plague (Exod 10:12-20).
Richard Patterson traced Exodus Motif in the Prophets, showing that the Exodus was a significant source of imagery for the rest of the Old Testament. The reason for this is the common “Divine Warrior” and “Divine Redeemer” themes in the Prophets. In the Exodus events, God fought for this people in order to redeem them out of their slavery. The prophets pick up those twin themes and apply them to their current situation. Israel has persisted in their unbelief and is once again under oppression (the Exile). God will once again fight for them and redeem them from the nations in a New Exodus.
While Patterson’s article does not continue to follow his argument into the Second Temple Period, the New Exodus theme is present in this literature. But plague imagery is not as common in Jewish sources as we might have guessed. In his detailed survey of the imagery of the Exodus in later Jewish writings, David Aune only finds the plagues in an eschatological sense in the Apocalypse of Abraham. There are ten plagues, although they do not track with the original ten plagues or the seven trumpets from Revelation.
Apoc. Abr. 30:3-8 And he said to me, “I will explain to you the things you desired in your heart, for you have sought to know the ten plagues which I prepared against the heathen, and I prepared them beforehand in the passing of the twelve hours on earth. Hear what I tell you, it will be thus. The first: sorrow from much need. The second: fiery conflagrations for the cities. The third: destruction by pestilence among the cattle. The fourth: famine of the world, of their generation. The fifth: among the rulers, destruction by earthquake and the sword. The sixth: increase of hail and snow. The seventh: wild beasts will be their grave. The eighth: pestilence and hunger will change their destruction. The ninth: execution by the sword and flight in distress. The tenth: thunder, voices, and destroying earthquakes.” (Rubinkiewicz, OTP 1:704)
Nevertheless, Revelation seems to be re-using imagery from the Ten Plagues. Since John is standing on the shoulders of the Hebrew Bible. This is not a surprise. But it is important to at least wonder why it is important that the Exodus Events were chosen as the main backdrop for John’s apocalyptic description in Revelation 8-9. The purpose of the original ten plagues was for God to show his power to Israel. The ten plagues were not “evangelistic,” hoping that the Egyptians would see them and somehow “convert” to being Jewish. The plagues prove to the people of God in Egypt that he is a God who acts on their behalf to redeem them out of their slavery. The children of Abraham need to be convinced that the God of their ancestors is active and that he cares for them.
This may also be the function of the judgments in Revelation. By the time of the eschatological age, Israel will have been in a state of unbelief for a long time. Like the original Exodus, they certainly need a reminded of the righteous character of their God. Revelation is using the language of the Hebrew Bible, how God has worked in the past, to describe how he will work again in the future.
