The Psalmist, often is harassed by the enemy, and therefore desires an escape. He knows that God is His strength, so resorts to "cause me to escape," and asks for the authority to God to make Him hear.
Psalm 71:1-3 "In thee, O LORD, do I put my trust: let me never be put to confusion. Deliver me in thy righteousness, and cause me to escape: incline thine ear unto me, and save me. Be thou my strong habitation, whereunto I may continually resort: thou hast given commandment to save me; for thou art my rock and my fortress."
