Exodus 4:13

"And he said, Oh Lord, Send, I pray thee, by the hand of him whom thou wilt send."

This means, "Oh Lord, send anybody but me!" Despite all that the Lord had done to encourage and strengthen Moses' faith, he still felt a great reluctance to undertake so difficult and important a mission. Note how this contrasts with the eagerness with which Moses, forty years earlier, had presented himself as the champion of Israel, thinking that perhaps in his personal strength he might be able to deliver them. All of that former confidence was absent from his thoughts at this point. The great lesson which he was just at the point of comprehending was that it would not be Moses, but GOD, who would effect their actual deliverance.
