And Moses spoke before the Lord, saying, Behold, the children of Israel hearkened not to me, and how shall Pharaoh hearken to me? And I am not eloquent.

And Moses said to the Lord, I pray, Lord, I have not been sufficient in former times, neither from the time that You have begun to speak to Your servant: I am weak in speech, and slow-tongued.

For if I preach the gospel, there is nothing for me to boast about, for necessity is pressed upon me; yes, woe is me if I do not preach the gospel!

For if I do this willingly, I have a reward; but if unwillingly, I have been entrusted with a commission.
