'Promise' in the Bible

Then they said, "We will restore them, and will require nothing of them; so will we do, even as you say." Then I called the priests, and took an oath of them, that they would do according to this promise.

Also I shook out my lap, and said, "So may God shake out every man from his house, and from his labor, that doesn't perform this promise; even thus be he shaken out, and emptied." All the assembly said, "Amen," and praised Yahweh. The people did according to this promise.
