Wisdom 2:3

3 Which being extinguished, our body shall be turned into ashes, and our spirit shall vanish as the soft air,

Wisdom 2:3 In-Context

1 For the ungodly said, reasoning with themselves, but not aright, Our life is short and tedious, and in the death of a man there is no remedy: neither was there any man known to have returned from the grave.
2 For we are born at all adventure: and we shall be hereafter as though we had never been: for the breath in our nostrils is as smoke, and a little spark in the moving of our heart:
3 Which being extinguished, our body shall be turned into ashes, and our spirit shall vanish as the soft air,
4 And our name shall be forgotten in time, and no man shall have our works in remembrance, and our life shall pass away as the trace of a cloud, and shall be dispersed as a mist, that is driven away with the beams of the sun, and overcome with the heat thereof.
5 For our time is a very shadow that passeth away; and after our end there is no returning: for it is fast sealed, so that no man cometh again.
