Exodus 8 "Frogs Lice and Flies"

Exodus 8:32 "And Pharaoh hardened his heart at this time also, neither would he let the people go."

Chapter 8 tells of three rounds of plagues: frogs, lice, and flies. Pharaoh asked Moses to entreat the Lord for him that they be removed and Moses did but Pharaoh hardened his heart and would not let them go.

Frogs v5-15
Lice v16-19
Flies v20-32

One thing I noticed in this chapter is that Pharaoh has begun to acknowledge the Lord. v28 "And Pharaoh said, I will let you go, that ye may sacrifice to the Lord your God in the wilderness; only ye shall not go very far away; entreat for me."

The command from Moses was for a three day journey, nevertheless, Moses entreated the Lord to removed the flies. Pharaoh did not let them go.

Proverbs 3:19-20 "The Lord by wisdom hath founded the earth; by understanding hath he established the heavens. By his knowledge the depths are broken up, and the clouds drop down the dew."
