Verses 28-30 “28And it came to pass on the day when the LORD spake unto Moses in the land of Egypt,
29That the LORD spake unto Moses, saying, I am the LORD: speak thou unto Pharaoh king of Egypt all that I say unto thee.
30And Moses said before the LORD, Behold, I am of uncircumcised lips, and how shall Pharaoh hearken unto me?”

Moses spent much of his time objecting to God’s plan for him. It is a very good idea to get some spiritual issues solved and settled as early as possible. We can not move forward for God until we make God’s plan our own.
