Why then do not the Jews still possess a land thus eternally given them? Because God never bestows anything unconditionally. The land was bestowed upon them by virtue of a covenant Genesis 17:7; the Jews had broken the conditions of this covenant Jeremiah 7:5-6, and the gift reverted to the original donor.
Then (b) will I cause you to dwell in this place, in the land that I gave to your fathers, for ever and ever.
(b) God shows on what condition he made his promise to this temple that they would be a holy people to him, as he would be a faithful God to them.
Then will I cause you to dwell in this place,.... In the land of Judea, and not suffer them to be carried captive, which they had been threatened with, and had reason to expect, should they continue in their sins, in their impenitence and vain confidence:
in the land that I gave to your fathers; to Abraham, Isaac, and Jacob, by promise; and to the Jewish fathers in the times of Joshua, by putting them in actual possession of it:
for ever and ever: for a great while; a long time, as Kimchi explains it; from the days of Abraham for ever, even all the days of the world, provided they and their children walked in the ways of the Lord. This clause may either be connected with the word "dwell", or with the word give; and the sense is, either that they should dwell in it for ever and ever; or it was given to their fathers for ever and ever.
