Psalms 9:13

Have mercy upon me, O Lord -The cry for mercy implies that though God had interposed and granted them surprising deliverances, yet he was still surrounded by enemies, and was still in trouble. See introduction to the psalm, 2, 3. He had been delivered from many troubles, but there were many still pressing upon him, and he now calls on God to interpose further in his behalf, and to grant him entire deliverance from all his sorrows and dangers. The trouble to which he here refers was of the same kind as that adverted to in the former part of the psalm - that arising from the efforts of formidable enemies.
