'Witnesses' in the Bible

And I subscribed the writing, and sealed it, and took witnesses, and weighed the money in the balances.

and I gave the writing of the purchase unto Baruch the son of Nerijah, the son of Maaseiah, in the sight of Hanameel mine uncle's son, and in the presence of the witnesses that had subscribed the writing of purchase, before all the Jews that were sitting in the court of the guard.

And thou, Lord Jehovah, thou hast said unto me, Buy for thyself the field for money, and take witnesses; and the city is given into the hand of the Chaldeans.

Men shall buy fields for money, and subscribe the writings, and seal them, and take witnesses, in the land of Benjamin, and in the environs of Jerusalem, and in the cities of Judah, and in the cities of the hill-country, and in the cities of the lowland, and in the cities of the south: for I will turn their captivity, saith Jehovah.
