John Trapp on Psalms 9:13

Verſ. 13. Have mercy upon me, O Lord, &c.] Theſe are the words (ſay ſome) of thoſe humble ones whom God forgetteth not; they were Gods remembrancers. See Iſa. 62.6. or, it is a prayer of David for further deliverances, according to that, I will call upon the Lord, who is worthy to be praiſed, Pſal. 18.3. Betwixt prayſing and praying he divided his time, and drove an holy trade between Heaven and Earth.

Thou that lifteſt me up from the gates of death] i.e. Ex praeſentiſſimo & certiſſimo interitu, from deſperate and deadly dangers, ſuch as threaten preſent deſtruction; and ſhew a man the Grave even gaping for him. David was oft at this paſs; and God delivered Paul from ſo great a death, 2 Cor. 1.10. he commonly reſerveth his hand for a dead lift, and reſcueth thoſe who were even talking of their Graves.
