KJV: {To the chief Musician, even to Jeduthun, A Psalm of David.} I said, I will take heed to my ways, that I sin not with my tongue: I will keep my mouth with a bridle, while the wicked is before me.
NASB: For the choir director, for Jeduthun. A Psalm of David. I said, "I will guard my ways That I may not sin with my tongue; I will guard my mouth as with a muzzle While the wicked are in my presence."
KJV: Against thee, thee only, have I sinned, and done this evil in thy sight: that thou mightest be justified when thou speakest, and be clear when thou judgest.
NASB: Against You, You only, I have sinned And done what is evil in Your sight, So that You are justified when You speak And blameless when You judge.
