God didn't just hand Moses a script and walk away. He established a divine partnership, involving both Moses and Aaron, to accomplish His purposes.
This passage shows a beautiful picture of divine collaboration. God assigns Moses the task of relaying His message to Aaron, essentially 'putting words in his mouth.' Then, God promises to be present with both their mouths.
A Shared Responsibility
This isn't just about Moses dictating and Aaron speaking. It's about God working through both of them. Moses, despite his own struggles, is tasked with instructing Aaron, and Aaron, the eloquent speaker, is to be the voice. God’s presence ensures that the message is right, the delivery is effective, and the action taken is according to His will. It’s a reminder that God often works through multiple people, each with unique gifts, towards a common goal.
