13   And Moses said unto the people, Fear ye not, stand still, and see the salvation of the LORD, which he will shew to you to day: for the Egyptians whom ye have seen to day, ye shall see them again no more for ever.    14   The LORD shall fight for you, and ye shall hold your peace.    15   And the LORD said unto Moses, Wherefore criest thou unto me? speak unto the children of Israel, that they go forward: ~ EXODUS 14:13-15

“Wherefore criest thou unto me?” Moses had not been crying unto the Lord, or had he? It was his declaring, “HE will shew you to day”, rather than recognizing that he already had the commission to lead the Children of Israel back to Sinai. God had proved him over and over, and now he stands before the Red Sea with no revelation that it is done. Notice, when God rebuked him, He didn’t say, “Tell the Red Sea to part”. He said “Speak unto the Children of Israel, that THEY go forward”. The commission was to bring the Children of Israel back, and whatever laid  in that way had to move.
