Exodus 4:10

O my Lord, I am not eloquent — He was a great philosopher, statesman, and divine, and yet no orator; a man of a clear head, great thought and solid judgment, but had not a voluble tongue, nor ready utterance; and therefore he thought himself unfit to speak before great men, and about great affairs. Moses was mighty in word, Acts 7:22, and yet not eloquent: what he said was strong and nervous, and to the purpose, and distilled as the dew, Deuteronomy 32:2, though he did not deliver himself with that readiness, ease and fineness that some do.
