Exodus 7

The chapter begins with Moses doubting himself as a speaker. God reemphasizes that He will speak directly to Moses, and that Moses will communicate the message to Aaron. Aaron will perform the speaking role, and they will work as a unit to confront Pharoah.

Moses and Aaron are unemployed, non-wealthy octogenarians, Aaron being slightly older.

They perform the snake miracle, and Pharoah's magicians replicate the feat. Pharaoh's heart was hardened and he did not listen. They were empowered to turn the drinking water in Egypt to blood. Pharaoh's magicians were able to replicate that as well, which reduced the significance to Pharaoh.

He still would not let the Hebrews leave for three days.
