Chapter 141 in Tehillim is one of Dovid's prayers when Shaul was chasing him. What did Dovid mean when he refers to, 'oil on my head'? What important lesson can we learn from this. Chapter 142 in Tehillim is, 'Maskil L'Dovid', which is traditionally said in times of difficulty. When did Dovid say this Mizmor? How does this affect the way we understand this Mizmor? Chapter 143 in Tehillim is another prayer. Is this Mizmor a personal prayer of Dovid's? Or is it a prayer of the Jewish People in exile?
