4. It shall change their note, and mar all their mirth (v. 10): I will turn your feasts into mourning, as (v. 3) the songs of the temple into howlings. Note, The end of the sinner's mirth and jollity is heaviness. As to the upright there arises light in the darkness, which gives them the oil of joy for mourning, so on the wicked there falls darkness in the midst of light, which turns their laughter into mourning, their joy into heaviness. So great, so general, shall the desolation be, that sackcloth shall be brought upon all loins, and baldness upon every head, instead of the well-set hair and the rich garments they used to wear. The mourning at that day shall be as mourning for an only son, which denotes the most bitter and lasting lamentation. But are there then no hopes that when things are at the worst they will mend, and that at evening time it will yet be light? No, even the end thereof shall be as a bitter day, a day of bitter mourning; that state of impenitent sinners grows worse and worse, and the last of all will be the worst of all. This shall you have at my hand, you shall lie down in sorrow.
