Let truth be
Let all things you say be the truth and be no part of a lie.
The Holy Ghost, whom I have sent unto you, is the Spirit of Truth.
The Devil is the Father of all liars.
Speak the truth.
Live by the truth.
Abide in the truth.
Hold to the truth.
Let truth be the guiding Light of your life.
Be known to all men and the angels of Heaven as a truthful one.
It is not good, that out of the same fountain both bitter and sweet waters should flow.
Let every word you speak be the truth.
