Exodus 18:9
Then Jethro rejoiced for all the good which the Lord had done for Israel, who He delivered out of the hand of the Egyptians.
Jethro, Moses father-in-law heard about the goodness of God toward Israel and he came with Moses’ wife and sons to reunite them at the mountain of God. Moses shared with Jethro details about the stories Jethro heard before coming to meet Moses. Jethro was impressed and offered a sacrifice to God, acknowledging that the Lord was greater than all other gods. Everything that the devil did to Israel through Pharaoh was bad. All that the Lord did for Israel was good. The devil is all bad and God is all good.
