Exodus 4:1-14

And Moses answered and said, But, behold, they will not believe me, nor hearken unto my voice; for they will say, Jehovah hath not appeared unto thee. And Jehovah said unto him, What is that in thy hand? And he said, A rod. And he said, Cast it on the ground. And he cast it on the ground, and it became a serpent; and Moses fled from before it. And Jehovah said unto Moses, Put forth thy hand, and take it by the tail: (and he put forth his hand, and laid hold of it, and it became a rod in his hand); that they may believe that Jehovah, the God of their fathers, the God of Abraham, the God of Isaac, and the God of Jacob, hath appeared unto thee. And Jehovah said furthermore unto him, Put now thy hand into thy bosom. And he put his hand into his bosom: and when he took it out, behold, his hand was leprous, as white as snow. And he said, Put thy hand into thy bosom again. (And he put his hand into his bosom again; and when he took it out of his bosom, behold, it was turned again as his other flesh.) And it shall come to pass, if they will not believe thee, neither hearken to the voice of the first sign, that they will believe the voice of the latter sign. And it shall come to pass, if they will not believe even these two signs, neither hearken unto thy voice, that thou shalt take of the water of the river, and pour it upon the dry land: and the water which thou takest out of the river shall become blood upon the dry land. And Moses said unto Jehovah, Oh, Lord, I am not eloquent, neither heretofore, nor since thou hast spoken unto thy servant; for I am slow of speech, and of a slow tongue. And Jehovah said unto him, Who hath made man’s mouth? or who maketh a man dumb, or deaf, or seeing, or blind? is it not I, Jehovah? Now therefore go, and I will be with thy mouth, and teach thee what thou shalt speak. And he said, Oh, Lord, send, I pray thee, by the hand of him whom thou wilt send. And the anger of Jehovah was kindled against Moses, and he said, Is there not Aaron thy brother the Levite? I know that he can speak well. And also, behold, he cometh forth to meet thee: and when he seeth thee, he will be glad in his heart.
