John Trapp on Psalms 25:5

Verſ. 5. Lead mee in thy Truth, and teach mee] i. e. Aſſiduè doce & urge. David was a great proficient in Gods School, and yet he would learn more: ſo ſweet is divine knowledge. Four times together here, prayeth. David to bee further inſtructed. See Moſes in like manner holily encroaching upon God, Exod. 33.12, 13, 16, 18. as if his Motto had been that of Charles the fiſth, Vlterius, More yet.

For thon art the God of my ſalvation] Perfect therefore that which concerneth mee; Thy mercy O Lord endureth for ever; forſake not the works of thine own hands, Pſal. 138.8. Thou haſt written mee down in thy book of preſervation with thine own hand; oh read thine own hand-writing and ſave mee, ſaid Queen Elizabeth in her troubles.
