'I Will Be with You' in the Bible

He said, "Certainly I will be with you. This will be the token to you, that I have sent you: when you have brought forth the people out of Egypt, you shall serve God on this mountain."

Now therefore go, and I will be with your mouth, and teach you what you shall speak."

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