'Witnesses' in the Bible

And take true witnesses to the writing, Uriah the priest, and Zechariah, the son of Jeberechiah.

Let all the nations come together, and let the peoples be present: who among them is able to make this clear, and give us word of earlier things? let their witnesses come forward, so that they may be seen to be true, and that they may give ear, and say, It is true.

You are my witnesses, says the Lord, and my servant whom I have taken for myself: so that you may see and have faith in me, and that it may be clear to you that I am he; before me there was no God formed, and there will not be after me.

I gave the word, and made it clear, and there was no strange god among you: for this reason you are my witnesses, says the Lord.

Even the people whom I made to be the witnesses of my praise.

Have no fear, be strong in heart; have I not made it clear to you in the past, and let you see it? and you are my witnesses. Is there any God but me, or a Rock of whom I have no knowledge?
