Ecclesiastes 12:6-7

[Remember your Creator earnestly now] before the silver cord [of life] is snapped apart, or the golden bowl is broken, or the pitcher is broken at the fountain, or the wheel broken at the cistern [and the whole circulatory system of the blood ceases to function]; Then shall the dust [out of which God made man's body] return to the earth as it was, and the spirit shall return to God Who gave it.
