They’re different from the curses to Israelites as mentioned in Leviticus.
Some have connected the Egyptian plagues to natural phenomena that were possible in ancient Egypt.
A second view of the Biblical plagues sees them as attacks on the pantheon of Egyptian gods.
Accordingly, the first plague described in Exodus in the Bible—turning the waters of Egypt to blood—is directed against one of several gods associate with Nile or with water.
Some of the plagues are the type of disasters that recur often in human history—hailstorms and locusts—and therefore appear possible and realistic.
Others, less realistic, border on the comic—frogs and lice.
This painting, “He turned their waters into blood,” by the 19th-century American folk painter Erastus Salisbury Field (1805–1900), depicts the first of the Biblical plagues inflicted on the Egyptians.
One understanding of the Egyptian plagues explains them as expressions of natural events.For example, Heket was represented as a frog and Hathor as a cow.An ancient Egyptian “Coffin Text” refers to the slaying of first-born gods.On this count ten could be connected to the ten divine utterances of the creation account of Genesis 1.In relating the ten Egyptian plagues, the Exodus in the Bible could represent a parallel account of liberation, affecting all aspects of the created world.In the 12th century, a rabbi known as the Rashbam (Rabbi Samuel ben Meir), who lived in northern France, recognized that only certain plagues were introduced by warnings to Pharaoh, while others were not.
