What does the Bible say about miracles in Exodus?

In Exodus, miracles serve a dual purpose: they showcase God's sovereignty and power while also providing a divine warning to Pharaoh. When Moses and Aaron perform miracles, such as turning a rod into a serpent, they illustrate God's might over the Egyptian magicians, who can merely duplicate the signs. This highlights that while God's miracles compel a response, they do not have the capacity to soften hardened hearts, as seen with Pharaoh. God's intent was not to convert Pharaoh but to demonstrate His authority and lead to eventual liberation of the Israelites through the plagues.
