Although I don’t think God would use so many words to describe excuses as the coach mentioned above did, but in this dialogue between God and Moses, I can see where frustration happens when his people make excuses to commands.
The Bible is filled with many obedient servants; maybe the great leaders came to mind. Moses is one of those servants who was an impacting force very early on.
When we think of Moses, we think of the image of the nostalgic Prince of Egypt or even a rustic looking image of a man with a long white beard and his hair blowing in the wind. Moses is visually portrayed in a victorious and mighty way. Even though he was such a great leader and servant of God, people commonly forget that at first he gave God excuses.
The first couple of verses in chapter four frame the conversation between God and Moses; God shows Moses the various signs of his miracles to prove that the Lord is the one who sent him. God is proving his faithfulness to Moses and is asking Moses to reciprocate.
At first, Moses gives the run around of “what if’s….” to try to get out of doing what God is asking. Then, Moses understands God’s power, but gives excuses for why he is the wrong person for this job.
It’s funny how God works through people who reluctantly serve. Moses’ doubts are justified. Look to the passages prior to chapter four and it reveals what God was asking of Moses. He told Moses to go into Egypt and free his people. It makes sense why Moses had doubts and was pretty hesitant to this idea.
