'Witness' in the Bible

See that you say nothing to any man: but go and let the priest see you, and make yourself clean by an offering of the things ordered by Moses, for a witness to them.

And whatever place will not take you in and will not give ear to you, when you go away, put off the dust from your feet as a witness against them.

You have knowledge of what is said in the law, Do not put any one to death, Do not be untrue in married life, Do not take what is not yours, Do not give false witness, Do not get money by deceit, Give honour to your father and mother.

Then some got up and gave false witness against him, saying,

And even so their witness was not in agreement.

And they went out, preaching everywhere, the Lord working with them, and giving witness to the word by the signs which came after. So be it.
