I have not the means yet of clearing up particularly the force of Olam, verse 11. But the force of verse 21 is stronger than I supposed, "Who knoweth the spirit of a man?" It, which ascends upward, and the spirit of a beast, it, which descends downward to the earth? It is a sad ignorance no doubt, but it affirms very distinctly that man's spirit goes up—the beast's descends downwards to the earth, is lost in the material creation in a way unknown to us. He does not know what becomes of man's spirit neither, but it does go up to what is out of, and above the earth. Ya-da (knew)—acquainted with—the knowledge we have in ourselves—I know—I have the knowledge of the thing in my mind; there is also na-char (recognized); compare chap. 12:7.
