These verses verify that this "burden" (oracle) is upon Jerusalem. These examples of their vain preparations show that no matter how much one prepares for battle, or thinks to win in their own mind, that if God has not blessed it and it's not His Will, then it will not happen. These thought to worship own works, and not God.
     I hear many misapply;

 

 1 John 5:14: And this is the confidence that we have in Him, that if we ask anything according to His will, He heareth us:

 

As to our prayers being answered also, they most often leave off a very important condition of prayer being answered by The Father through The Son. What we pray for must first be in God's Will, for it to be granted. If it's not, then He will not 'hear' it. So how do we know what we pray for is His Will for us or not? Those who study His Word for themselves have a definite advantage in knowing that over those who do not study. Learning and understanding His Word is how we know to be in His Will. By these Old Testament examples of His People, aren't they still object lessons for us today? Learn then, how God's People of the past fell out of His Will, such as Judah did here in Isaiah 22, as many of both 'houses' still do today. Look upon GOD as the Maker, and not man's hands, nor the wizards who lead man astray to false worship.

Isa 22:12   And in that day did the Lord GOD of hosts call to weeping, and to mourning, and to baldness, and to girding with sackcloth:
13    And behold joy and gladness, slaying oxen, and killing sheep, eating flesh, and drinking wine: "let us eat and drink; for tomorrow we shall die."

     This 'baldness' and 'weeping' shows a state of lamentation, even as Job would tear his garment and shave his head in his time of trouble.

 

 Job 1:20:

 

 Job did not lay blame upon God for his sufferings. There's the difference. But this type here in Isaiah, many of them have even fallen into Satan's role of false accuser, heeding the world's lies in curses against God.

 

 Rev.12:10.

 

How so? Recall those of...

 

 Rev.16:9.

 

Whom God punishes on the fourth vial, which also refuses to repent, but "blasphemed the name of God" instead? We also covered this event back in Isaiah 8:18-22 about those of God's children which listen to the "wizards that peep, and that mutter". The very same "accuser of our brethren", i.e., Satan, wishes for us to believe that God creates and does evil upon us. God will remove His Protection from those who refuse Him allowing persecution, but He is not the one who does the evil.
     The Book of Job is a lesson for the blasphemy of those who would cause us to think God creates evil, just because He also created Lucifer.

 

Ezekiel 28:

 

Through the majority of the Book of Job, his three buddies tried to get him to admit sin which they thought caused his sad state of trouble. The only thing our Heavenly Father did was to allow Satan to tempt Job, temporarily removing His Hand of Protection over His servant.
