What was the immediate reaction of Moses when he cast his rod on the ground at Mount Hored and it became a serpent?

When Moses cast his rod on the ground at Mount Horeb and it became a serpent, he fled from it. According to the Bible, when God appeared to Moses in the form of a burning bush and called him to lead the Israelites out of Egypt, Moses doubted his ability to do so. So, God gave him several signs and miracles to perform to demonstrate His power and presence with him. One of these signs was turning Moses' rod into a serpent. When Moses cast his rod on the ground and it became a serpent, he was afraid and fled from it. However, God instructed him to take the serpent by the tail, and when he did, it turned back into a rod. This sign was meant to demonstrate God's power and authority over all things, including the natural world.
