9:12-22 In Zion the voice of joy and praise used to be heard, while the people kept close to God; but sin has altered the sound, it is now the voice of lamentation. Unhumbled hearts lament their calamity, but not their sin, which is the cause of it. Let the doors be shut ever so fast, death steals upon us. It enters the palaces of princes and great men, though stately, strongly built, and guarded. Nor are those more safe that are abroad; death cuts off even the children from without, and the young men from the streets. Hearken to the word of the Lord, and mourn with godly sorrow. This alone can bring true comfort; and it can turn the heaviest afflictions into precious mercies.
12. Rather, "Who is a wise man? (that is, Whosoever has inspired wisdom, 2Pe 3:15); let him understand this (weigh well the evils impending, and the causes of their being sent); and he to whom the mouth of the Lord hath spoken (that is, whosoever is prophetically inspired), let him declare it to his fellow countrymen," if haply they may be roused to repentance, the only hope of safety.
