My glory was fresh in me - Margin, “new.” “As we say, the man shall not overlive himself.” Umbreit. The idea is, that he was not exhausted; he continued in vigor and strength. The image is probably taken from that suggested in the previous verse - from a tree, whose beauty and vigor were continued by the waters, and by the dew that lay on its branches.
And my bow - An emblem of vigor and strength. The ancients fought with the bow, and hence, a man who was able to keep his bow constantly drawn, was an image of undiminished and unwearied vigor; compare Genesis 49:24 : “But his bow abode in strength.”
Was renewed in my hand - Margin, as in Hebrew “changed.” The meaning is, that it constantly renewed its strength. The idea is taken from a tree, which “changes” by renewing its leaves, beauty, and vigor; Isaiah 9:10; compare Job 14:7. The sense is that his bow gathered strength in his hand. The figure is very common in Arabic poetry, many specimens of which may be seen in Schultens in loc.
