'Witnesses' in the Bible

And I took unto me to witness, sure witnesses, Urijah the priest, and Zechariah the son of Jeberechiah.

Let all the nations be gathered together, and let the peoples be assembled: who among them declareth this, or causeth us to hear former things? let them bring forth their witnesses, that they may be justified; or let them hear, and say, It is truth.

Ye are my witnesses, saith Jehovah, and my servant whom I have chosen; that ye may know and believe me, and understand that I am HE: before me there was no God formed, neither shall there be after me.

It is I that have declared, and have saved, and have shewed, when there was no strange god among you; and ye are my witnesses, saith Jehovah, that I am God.

Fear not, neither be afraid. Have I not caused thee to hear from that time, and have declared it? and ye are my witnesses. Is there a +God beside me? yea, there is no Rock: I know not any.

They that form a graven image are all of them vanity, and their delectable things are of no profit; and they are their own witnesses: they see not, nor know; that they may be ashamed.
