Psalms 104:30 - Ellicott's Commentary On The Whole Bible

Spirit. — Rather, breath, as in Psalms 104:29. We must not here think of the later theological doctrine of the Holy Spirit. The psalmist evidently regards the breath of God only as the vivifying power that gives matter a distinct and individual, but transient, existence. Even in the speculative book of Ecclesiastes, the idea of a human soul having a permanent separate existence does not make its appearance. At death the dust, no longer animate, returns to the earth as it was, and the breath, which had given it life, returns to God who gave it — gave it as an emanation, to be resumed unto Himself when its work was done. Still less, then, must we look in poetry for any more developed doctrine.
