"Look to the right and see, for there is no one who takes notice of me" etc. What is "look to the right and see, for there is no one who takes notice of me"? It means that I have no one to rely on except You, who stand on my right side. This is what Your art teaches, that You are the right hand of the poor. As it is written, "For he shall stand at the right hand of the needy, to save him from those that judge his soul." Therefore it is said, "Look to the right and see." "I have no escape; no one cares for my life" etc. David said, "If I seek refuge, I will seek it not from the wicked, nor from Saul, nor from all Israel at this time." Therefore it is said, "I have no escape; no one cares for my life."
