Exodus 18:19

And Moses brought their cause before the Lord.

(I stood between the Lord and you at that time, to shew you the word of the Lord: for ye were afraid by reason of the fire, and went not up into the mount;) saying,

And they said unto Moses, Speak thou with us, and we will hear: but let not God speak with us, lest we die.

And he said, Certainly I will be with thee; and this shall be a token unto thee, that I have sent thee: When thou hast brought forth the people out of Egypt, ye shall serve God upon this mountain.

And the Lord was with Joseph, and he was a prosperous man; and he was in the house of his master the Egyptian.

Then thine handmaid said, The word of my lord the king shall now be comfortable: for as an angel of God, so is my lord the king to discern good and bad: therefore the Lord thy God will be with thee.

When thou goest out to battle against thine enemies, and seest horses, and chariots, and a people more than thou, be not afraid of them: for the Lord thy God is with thee, which brought thee up out of the land of Egypt.

And Moses said unto his father in law, Because the people come unto me to enquire of God:

So Moses hearkened to the voice of his father in law, and did all that he had said.

Now therefore go, and I will be with thy mouth, and teach thee what thou shalt say.

And he shall be thy spokesman unto the people: and he shall be, even he shall be to thee instead of a mouth, and thou shalt be to him instead of God.

Have not I commanded thee? Be strong and of a good courage; be not afraid, neither be thou dismayed: for the Lord thy God is with thee whithersoever thou goest.

Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world. Amen.

Give instruction to a wise man, and he will be yet wiser: teach a just man, and he will increase in learning.
