"My nervous system was prostrated, and my hand trembled so that I made but little progress in writing, and could get no farther than the simple copies in coarse hand. As I endeavored to bend my mind to my studies, the letters in the page would run together, great drops of perspiration would stand upon my brow, and a faintness and dizziness would seize me. I had a bad cough, and my whole system seemed debilitated. LS 19.1"
"For my life is spent with grief, and my years with sighing: my strength faileth because of mine iniquity, and my bones are consumed."
Both passages describe physical weakness and suffering. The EGW passage details nervous system issues and physical debilitation, while the Psalm speaks of grief, sighing, and failing strength. The connection is thematic and reasonably strong.
