Who or what are the host of heaven?

Question from moody radio listener on 2 September 2017: We are looking at Isaiah 24: 21 : " So it will happen in that day that the Lord will punish the host of heaven on high and the kings of the earth on earth. Who or what are the host of heaven?" Passages to be considered: Isaiah 24 21 And it shall come to pass in that day, that the Lord shall punish the host of the high ones that are on high, and the kings of the earth upon the earth.  -kjv 21 In that day the Lord will punish the powers in the heavens above and the kings on the earth below.  -niv 21 On that day the Lord will punish the host of heaven above and kings of the earth below.  -hcsb Psalms 2 2 The kings of the earth set themselves, and the rulers take counsel together, against the Lord, and against his anointed, saying, 3 Let us break their bands asunder, and cast away their cords from us.  -kjv 2 The kings of the earth rise up and the rulers band together against the Lord and against his anointed, saying, 3 “Let us break their chains and throw off their shackles.”  -niv 2 The kings of the earth take their stand, and the rulers conspire together against the Lord and His Anointed One: 3 “Let us tear off their chains and free ourselves from their restraints.” -hcsb Answer from Dr Michael Rydelnik: The simplest and clearest explanation is, " The host of heaven refers to the armies of heaven, so we often think of that as angels." It says the Lord will punish the host of heaven and this the moody bible commentary I am quoting now and exactly what I would have said if I did not have an mbc for me to look at, this is likely a reference to fallen angels or spiritual power that oppose God. So, the Lord will punish the host of heaven and the kings of the earth, referring to the political opposition to God in the last days, see psalm 2. Mrs Eva Rydelnik: The question isn't to so much why and who are they but why will they be punished? Answer from Dr Micheal Rydelnik: Obviously, the ultimate revolt when you think about it. The first revolt were the spiritual beings that revolted with Satan against God and although they were cast out, they still face ultimate punishment, the lake of fire was the destiny of the devil and his angels and then the kings of the earth are going to be punished if you read psalm 2 because they shake their fist at God and they want to throw off His rule and do whatever they want instead of what He wants.
