In Exodus 7:14-12:51, God sends 10 plagues to Egypt.
Some resources I've found online say that these plagues were jabs at the ineffectiveness of the Egyptian gods. Basically, it was a contest of Jehovah vs. the Egyptian gods.
With or without those sources, is it correct or even accurate to say that? The original text itself does not seem to hint at this at all. This exegesis seems to have been inferred years after these events happened.
