“You shall speak…” God told Moses in vs 2. “Aaron shall tell…” Moses and Aaron had a part to play.
But, God also made it clear that deliverance would come through him.
“I will bring my people out of the land of Egypt… (verse4.)
We are responsible for obedience and not outcome. We become overwhelmed when we don’t stay in our lane. When we try to do what only God can do. When we try to play the Holy Spirit in other people’s lives. Only God can do what only God can do.
Moses and Aaron brought truth. God brought deliverance.
