God told Moses to go back to Egypt and tell Pharaoh to let the Hebrews go so they could worship Him on Mount Horeb. The two to three million Hebrews were miserable as slaves and God wanted them to be free to worship Him and not be enslaved. The Lord had told Moses that Pharaoh would be obdurate and that only after wondrous deeds, terrible to the Egyptians, would the Hebrews be free.
Keep in mind that the Egyptians had many pagan deities. There were a large number of deities associated with agriculture, fertility, and protection. Our God, the true God, had distinguished Himself in Moses’s understanding of God by appearing to Moses and telling Moses His Name: I AM. God also gave Moses a staff and the assistance of his brother, Aaron to approach Pharaoh with the request to release the Hebrews from bondage. After the first request, Pharaoh said ‘no, they would not be released.’
Moses then asked the Lord in Exodus 5: 23 “Ever since I went to Pharaoh to speak in Your Name, he has maltreated this people of Yours, and You have done nothing to rescue them.”
Then the LORD answered Moses: Exodus 6: 1-3, “Now you shall see what I will do to Pharaoh. Forced by My mighty Hand, he will send them away, compelled by My outstretched Arm, he will drive them away from his land.” God also said to Moses, “I AM the LORD. As God the Almighty I appeared to Abraham, Isaac, and Jacob, but My Name, LORD, I did not make known to them.”
We note that in this last passage, the LORD, Himself is explaining how He is gradually revealing Himself to the people. First it was to Abraham and then his descendants, Isaac and later, Jacob. Once the Hebrews grew into a population of a few million in Egypt…then it was time for them to leave and become a new nation dedicated to the LORD in the promised land. Try to note and remember the progression…it shows that God leads us to Himself and has done this for every person since Adam and Eve. He gives us just the right amount of information to act out of faith to choose to love and worship Him with our own free will and not just that, He wants us to lead others to love and worship Him.
O LORD, may Your glorious Name be known in all the lands. Amen.
