Isaiah 39:7

7.Of thy sons It might be thought that this was far more distressing to Hezekiah, and therefore it is put last for the sake of heightening the picture. Even though any calamity spread widely in a nation, it is commonly thought that kings and their families will be exempted, as if they were not placed in the same rank with other men. When he understood, therefore, that his sons would be made captives and slaves, this must have appeared to him to be exceedingly severe. Hence again we may learn how much God was displeased with Hezekiah for seeking aid from earthly wealth, and boasting of it in the presence of wicked men, when God by a dreadful example punishes it as an unpardonable crime, that Hezekiah made an ambitious display of his wealth in presence of unbelievers.
