Ecclesiastes 12:6 - Joseph Benson’s Commentary on the Old and New Testaments

Or ever the silver cord be loosed By the silver cord he seems to understand the spinal marrow, which comes from the brain, and goes down to the lowest end of the back-bone. And this is aptly compared to a cord, both for its figure, which is long and round, and for its use, which is to draw and move the parts of the body; and to silver, both for its excellence and colour, which is white and bright, in a dead, much more in a living body. This may properly be said to be loosed, or dissolved, because it is relaxed, or otherwise disabled for its proper service. And answerably hereto, by the golden bowl we may understand the membranes of the brain, and especially that inmost membrane which insinuates itself into all the parts of it, following it in its various windings, keeping each parcel of it in its proper place, and dividing one from another, to prevent disorder. This is not unfitly called a bowl, because it is round, and contains in it all the substance of the brain; and a golden bowl, partly for its great preciousness and usefulness; partly for its ductility, being drawn out into a great thinness or fineness; and partly for its colour, which is somewhat yellow, and comes nearer to that of gold than any other part of the body does. And this, upon the approach of death, is commonly shrivelled up, and many times broken. And as these clauses concern the brain, and the animal powers, so the two following respect the spring of the vital powers, and of the blood, the great instrument whereof is the heart. And so Solomon here describes the chief organs appointed for the production, distribution, and circulation of the blood. For though the circulation of the blood has been hid for many generations, yet it was well known to Solomon. According to this notion, the fountain is the right ventricle of the heart, which is now acknowledged to be the spring of life; and the pitcher is the arteries which convey the blood from it to other parts, and especially that arterious vein, by which it is transmitted to the lungs, and thence to the left ventricle, where it is better elaborated, and then thrust out into the great artery, called aorta, and by its branches dispersed into all the parts of the body. And the cistern is the left ventricle of the heart, and the wheel seems to be the great artery, which is fifty so called, because it is the great instrument of this circulation. The pitcher may be said to be broken at the fountain, when the veins do not return the blood to the heart, but suffer it to stand still and cool, whence comes that coldness of the outward parts, which is a near forerunner of death. And the wheel may be said to be broken at the cistern, when the great arteries do not perform their office of conveying the blood into the left ventricle of the heart, and of thrusting it out thence into the lesser arteries, whence comes that ceasing of the pulse, which is a certain sign of approaching death.
