My heart panteth, my strength faileth me: as for the light of mine eyes, it also is gone from me.
My heart panteth - palpitates.
As for the light of mine eyes, it also is gone from me - literally, they also (are) not with me. The light of mine eyes-nay, mine eyes themselves-are not with me (Psalms 13:3, note; 1 Samuel 14:27; 1 Samuel 14:29). The lack-luster eye betrays the failure of the vital power.
