When the royal family of Judah was brought to desolation by the captivity of Jehoiachin and Zedekiah it might be asked, "What has now become of the covenant of royalty made with David, that his children should sit upon his throne for evermore? Do the sure mercies of David prove thus unsure?" To this it is sufficient for the silencing of the objectors to answer that the promise was conditional. If they will keep my covenant, then they shall continue, Ps. cxxxii. 12. But David's posterity broke the condition, and so forfeited the promise. But the unbelief of man shall not invalidate the promise of God. He will find out another seed of David in which it shall be accomplished; and that is promised in these verses.
