Exodus 4:15

You shall speak to him and put the words in his mouth , and I will be with your mouth and with his mouth and will teach you both what to do .

You shall speak to him and put words in his mouth; I will help both of you speak and will teach you what to do.

And thou shalt speak unto him, and put words in his mouth : and I will be with thy mouth, and with his mouth, and will teach you what ye shall do.
