'Promise' in the Bible

who hast kept with thy servant David my father that which thou didst promise him: yea, thou spakest with thy mouth, and hast fulfilled it with thy hand, as it is this day.

Blessed be Jehovah, that hath given rest unto his people Israel, according to all that he promised: there hath not failed one word of all his good promise, which he promised by Moses his servant.

Now, O Jehovah God, let thy promise unto David my father be established; for thou hast made me king over a people like the dust of the earth in multitude.

who hast kept with thy servant David my father that which thou didst promise him: yea, thou spakest with thy mouth, and hast fulfilled it with thy hand, as it is this day.

Then said they, We will restore them, and will require nothing of them; so will we do, even as thou sayest. 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 God shake out every man from his house, and from his labor, that performeth not this promise; even thus be he shaken out, and emptied. And all the assembly said, Amen, and praised Jehovah. And the people did according to this promise.

Is his lovingkindness clean gone for ever? Doth his promise fail for evermore?
