There are many physical blessings of God pronounced upon Israel. Every aspect of their life would be blessed but it would depend upon their obedience of the commandments of God and the covenant the made with Him. Disobedience would bring curses reaping what it sows. Prophecy does not bode well for the nation for the land shall mourn and nations will ask why and "what meaneth the heat of this great anger?" Yet, in the end the Lord does not retain his anger. He delights in mercy and a place is being prepared for those who fear Him and do His will.
