Exodus 4:1

Then Moses answered , But behold , they will not believe me or listen to my voice , for they will say , The Lord did not appear to you.

Moses answered, “What if they do not believe me or listen to me and say, ‘The Lord did not appear to you`?”

And Moses answered and said, But, behold, they will not believe me, nor hearken unto my voice : for they will say, The Lord hath not appeared unto thee.
