'Witness' in the Bible

because they have done a disgraceful thing in Israel, and they have committed adultery with the wives of their neighbors, and they have spoken words in my name, lies that I have not commanded them, and I [am] he who knows, and [I am] a witness,' {declares} Yahweh."

And I signed on the letter and sealed [it], and I called witnesses as witness, and I weighed out the money on a set of scales.

Yet you have said to me, Lord Yahweh, "Buy for yourself the field with the money, and call witnesses as witness," though the city has been given into the hand of the Chaldeans.'"

They will buy fields with money, and they will sign the deeds, and they will seal [them], and they will call witnesses as witness in the land of Benjamin, and in the surroundings of Jerusalem, and in the cities of Judah, and in the cities of the hill country, and in the cities of the Shephelah, and in the cities of the Negev, for I will restore their fortunes,' {declares} Yahweh."

Then they said to Jeremiah, "May Yahweh be against us as {a true and faithful witness} if we do not do according to all the words that Yahweh sends you for us.
