'Promise' in the Bible

And they said, We will restore them, and will require nothing of them; so will we do, as thou hast said. And I called the priests, and took an oath of them, that they should do according to this promise.

Also I shook my lap, and said, So God shake out every man from his house and from his earnings, that performeth not this promise: even thus be he shaken out and emptied! And all the congregation said, Amen! And they praised Jehovah. And the people did according to this promise.
