“The enemy has pursued me.
He has crushed my life to the ground.
He has made me sit in darkness
Like those long dead.
Therefore my spirit faints within me.
My heart within me is appalled.”
The situation of David is described as being pursued by his enemies. He seems like he has been crushed to the ground. He sat in darkness as if he were dead. His spirit was fainting as mentioned above. His heart was appalled. He was in bad shape.
