Nehemiah 5:12

Then said they, overcome by the force of the arguments used by Nehemiah, We will restore them, both the pledges and the interest exacted, and will require nothing of them; so will we do as thou sayest. Then I called the priests, as the representatives of the Lord, and took an oath of them, the priests administering this solemn oath, that they should do according to this promise, the men involved thus binding themselves before the face of Jehovah Himself.
