Exodus 3:11

What a mean, inconsiderable person am I! how unworthy and unfit for that employment! He was more forward in the work forty years ago, by reason of the fervours of his youth, his inexperience in affairs, the advantage of his power and interest in the court, by which he thought he could and should procure their deliverance; but now age had made him cool and considerate; the remembrance of his brethren's rejection of him, when he was a great man at court, took away all probability of prevailing with them to follow him, much more of prevailing with Pharaoh to let them go. Thus Moses falls into that distemper to which most men are prone, of measuring God by himself, and by the probabilities or improbabilities of second causes.
