no man cared for my soul.

"Psalm 142:
As the superscription indicates,
David’s distress this time is the dogged pursuit by his 
enemies.
“When
he was in the cave” could refer to the cave of Adullam (1 Sam. 22:1-2),
or En-gedi (1 Sam. 24:1-7).
After presenting his lament (verses 1-4),
David lifts up his petition (verses 5-6), and promises his thanksgiving
when God answers (verse 7).
I. Cry of David (142:1-2);
I cried unto the LORD with my voice; vs.1
II. Circumstances of David (142:3-4);
When my spirit was overwhelmed within me... vs.3
III. Confidence of David (142:5-7).
Bring my soul out of prison, that I may praise thy name: vs.7
Verses 1-2: David’s description of loneliness could be anyone’s: he is disoriented, deserted, depressed, and defeated."

Attend unto my cry; for I am brought very low:
deliver me from my persecutors; for they are stronger than I.
