on Job 27 :18
He buildeth his house as a moth - With great skill, great pains, and great industry; but the structure, however skillful, shall be dissolved; and the materials, however costly, shall be brought to corruption. To its owner it shall be only a temporary habitation, like that which the moth makes in its larve or caterpillar state, during its change from a chrysalis to a winged insect.
As a booth that the keeper maketh - A shed which the watchman or keeper of a vineyard erects to cover him from the scorching sun, while watching the ripening grapes, that they may be preserved from depredation. Travellers in the East have observed that such booths or sheds are made of the lightest and most worthless materials; and after the harvest or vintage is in, they are quite neglected, and by the winter rains, etc., are soon dissolved and destroyed.
on Job 27 :18
He buildeth his house as a moth - The house which the moth builds is the slight fabric which it makes for its own dwelling in the garment which it consumes. On this verse compare Job 8:14. The dwelling of the moth is composed of the materials of the garment on which it feeds, and there may be an allusion here not only to the fact that the house which the wicked reared for themselves would be temporary, and that it would soon pass away like the dwelling of the moth, but that it was obtained - like the dwelling of the moth - at the expense of others. The idea of frailty, however, and of its being only a very temporary habitation, is probably the main thought in the passage. The allusion here is to the moth-worm as it proceeds from the egg, before it is changed into the chrysalis, aurelia, or nymph. "The young moth, upon leaving the egg which a papilio has lodged upon a piece of stuff, or a skin well dressed, and commodious for her purpose, immediately finds a habitation and food in the nap of the stuff, or hair of the skin. It gnaws and lives upon the nap, and likewise builds with it its apartment, accommodated both with a front door and a back one: the whole is well fastened to the ground of the stuff, with several cords and a little glue. The moth sometimes thrusts her head out of one opening, and sometimes out of the other, and perpetually demolishes all about her; and when she has cleared the place about her, she draws out all the stakes of the tent, after which she carries it to some little distance, and then fixes it with her slender cords in a new situation."
Burder. It is to the insect in its larvae or caterpillar state that Job refers here, and the slightness of the habitation will be easily understood by anyone who has watched the operations of the silkworm, or of the moths that appear in this country. The idea is, that the habitation which the wicked constructed was temporary and frail, and would soon be left. The Chaldee and Syriac render this "the spider;" and so does Luther - Spinne. The slight gossamer dwelling of the spider would well correspond with the idea here expressed by Job.
And as a booth - A tent, or cottage.
That the keeper maketh - That one who watches vineyards or gardens makes as a temporary shelter from the storm or the cold at night. Such edifices were very frail in their structure, and were designed to be only temporary habitations; see the subject explained in the notes at Isaiah 1:8. Niebuhr, in his description of Arabia, p. 158, says, "In the mountains of Yemen they have a sort of nest on the trees, where the Arabs sit to watch the fields after they have been planted. But in the Kehama, where they have but few trees, they build a light kind of scaffolding for this purpose." Mr. Southey opens the fifth part of his Curse of Kehama with a similar allusion:
"Evening comes on: - arising from the stream
Homeward the tall flamingo wings his flight;
And when hc sails athwart the setting beam,
His scarlet plumage glows with deeper light.
The watchman, at the wish'd approach of night
Gladly forsakes the field, where he all day,
To scare the winged plunderers from their prey,
With shout and sling, on yonder clay-built height,
Hath borne the sultry ray.
on Job 27 :18
27:18 A moth - Which settleth itself in a garment, but is quickly and unexpectedly dispossessed of its dwelling, and crushed to death. A booth - Which the keeper of a garden or vineyard suddenly rears up in fruit - time, and as quickly pulls down again.
