My heart is smitten, and withered like grass; so that I forget to eat my bread.
My heart - the seat of vital power.
Is smitten, and withered like grass - when smitten by the sun (Psalms 121:6), or else when broken by any injury to the stem.
So that I forget to eat my bread - rather, as Hebrew х kiy (H3588)], 'FOR I forget to eat my bread:' assigning the cause of the heart or vital power becoming withered-namely, because my deep distress makes me, to loath my food, the usual strengthener of man's heart (Psalms 104:15; Psalms 107:18; 1 Samuel 1:7; 1 Samuel 20:34).
