Exodus 6 has Moses being reminded of just who he was talking with. After all, it is God Himself, and He has a plan. ”`”. God is not intimidated by Pharaoh. He knows exactly how to put him in his place. And most importantly, we get clarity about why this is so important. God says “I have remembered my covenant”. This isn’t something that has just come up all of a sudden due to some fervent prayers. This is about a covenant God made with Abraham decades ago.
Now it is time for God to act. He tells Moses to “Say therefore to the people of Israel, ‘I am the Lord, and I will bring you out from under the burdens of the Egyptians, and I will deliver you from slavery to them, and I will redeem you with an outstretched arm and with great acts of judgment….I will take you to be my people, and I will be your God, and you shall know that I am the Lord your God”. Here is the reminder of why this is happening. God has promised such, and He will do what He says.
So Moses goes to his people and “they did not listen to Moses….because of their broken spirit and harsh slavery”. After all, his track record isn’t too good. He told them they were being set free and next thing you know their workload multiplied. God tells them to go to Pharaoh and give him the message to let His people go. But again, Moses argues with God. He does not believe the message will be well received and has no interest in going back to face Pharaoh once more. But God “gave them a charge” and sends them in anyway.
At least so it seemed. “But Moses said to the Lord, “Behold, I am of uncircumcised lips. How will Pharaoh listen to me”? Moses has no intention of going back in there. He’s seen what happens when you try and throw your weight around with Pharaoh. It wasn’t a good outcome. Being a messenger for God isn’t quite the same as being God. And Pharaoh doesn’t know God anyway, nor care, so this won’t end where God intends. At least from Moses’ perspective. Problem is that Moses only sees a small piece of God’s plan. We never know the whol thing. We just need to obey what we’ve been told.
