'Promised' in the Bible

“Arise and depart [because the captivity is inevitable],For this [land] is not the place of restBecause of the defilement that brings destruction,A painful and terrible destruction.

But each man will sit under his grapevineand under his fig treewith no one to frighten him.For the mouth of the Lord of Hostshas promised this.

You will remain true to Jacob, and merciful to Abraham, as you promised our ancestors long ago.
