12:4 And the {f} doors shall be shut in the streets, when the sound of the {g} grinding shall be low, and he shall rise up at the voice of the {h} bird, and all the {i} daughters of music shall be brought low;
(f) The lips or mouth.
(g) When the jaws will scarce open and not be able to chew any more.
(h) He will not be able to sleep.
(i) That is the wind pipes or the ears will be deaf and not able to hear singing.
12:4 In - Or, towards the streets: which lead into the streets. This may be understood either of the outward senses, which, as doors, let in outward objects to the soul: or rather the mouth, the two lips, here expressed by a word of the dual number, which like a door, open or shut the way that leads into the streets or common passages of the body; which also are principal instruments both of speaking and eating. And these are said to be shut, not absolutely, but comparatively, because men in old age grow dull and listless, having little appetite to eat, and are very frequently indisposed for discourse. When the sound - When the teeth are loose and few, whereby both his speech is low, and the noise which he makes in eating is but small. Shall rise - From his bed, being weary with lying, and unable to get sleep. The bird - As soon as the birds begin to chirp, which is early in the morning, whereas young men, can lie and sleep long. The daughters - All those senses which are employed in music. Brought low - Shall be cast down from their former excellency, and become incapable either of making musick, or of delighting in it.
12:1-7 We should remember our sins against our Creator, repent, and seek forgiveness. We should remember our duties, and set about them, looking to him for grace and strength. This should be done early, while the body is strong, and the spirits active. When a man has the pain of reviewing a misspent life, his not having given up sin and worldly vanities till he is forced to say, I have no pleasure in them, renders his sincerity very questionable. Then follows a figurative description of old age and its infirmities, which has some difficulties; but the meaning is plain, to show how uncomfortable, generally, the days of old age are. As the four verses, 2-5, are a figurative description of the infirmities that usually accompany old age, ver. 6 notices the circumstances which take place in the hour of death. If sin had not entered into the world, these infirmities would not have been known. Surely then the aged should reflect on the evil of sin.
