'Witnesses' in the Bible

I signed the deed and sealed it, and called in witnesses, and weighed out the money on the scales.

and I gave the purchase deed to Baruch the son of Neriah, the son of Mahseiah, in the sight of Hanamel my uncle’s son and in sight of the witnesses who signed the purchase deed, in the presence of all the Jews who were sitting in the court of the guard.

Yet, O Lord God, You said to me, “Buy the field with money and get witnesses,” even though the city is given into the hands of the Chaldeans.’”

People will buy fields for money, sign deeds, seal them, and call in witnesses in the land of Benjamin, in the places around Jerusalem, in the cities of Judah, in the cities of the hill country, in the cities of the lowland, and in the cities of the South (the Negev); for I will restore their fortunes and release them from exile,’ says the Lord.”
