'Witness' in the Bible

The look of their face doth witness against them, and they declare their sin as Sodom: they hide it not. Woe unto their soul! for they have brought evil upon themselves.

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

and it shall be for a sign and for a witness to Jehovah of hosts in the land of Egypt; for they shall cry unto Jehovah because of the oppressors, and he will send them a saviour and defender, who shall deliver them.

Now go, write it before them on a tablet, and record it in a book, that it may be for the time to come, as a witness for ever,

Behold, I have given him for a witness to the peoples, a prince and commander to the peoples.
