Psalms 19:14 - Matthew Poole's English Annotations on the Holy Bible

Having prayed that God would keep him from sinful actions, he now prays that God would govern and sanctify his words and thoughts, wherein he had many ways offended, as he here implies, and oft in this book confesseth and bewaileth. And this he the rather doth, because this caution was very necessary to preserve him from presumptuous sins, which have their first rise in the thoughts, and thence proceed to words and expressions, before they break forth into actions. Be acceptable in thy sight, i.e. be really good and holy, and so well-pleasing to thee. My strength: O thou who hast hitherto strengthened me, both against my temporal and spiritual enemies, and whose gracious powerful assistance is absolutely necessary to keep me from my own corrupt inclinations, and from all temptations to sinful thoughts, and words, and actions. My redeemer: this expression seems to be added emphatically, and with special respect to Christ, who was certainly much in David's eyes, to whom alone this word Goel can here properly belong, as may appear See Poole on "Job 19:25", to which I refer the reader, and by whose blood and Spirit alone David could and did expect the blessings and graces for which he here prayeth.
