Psalms 50:6
Rahlfs Septuagint (1935) · Berean Standard Bible
σοὶ μόνῳ ἥμαρτον καὶ τὸ πονηρὸν ἐνώπιόν σου ἐποίησα ὅπως ἂν δικαιωθῇς ἐν τοῖς λόγοις σου καὶ νικήσῃς ἐν τῷ κρίνεσθαί σε
51:4
Against You, You only, have I sinned and done what is evil in Your sight, so that You may be proved right when You speak and blameless when You judge (note: LXX and victorious when You judge; cited in Romans 3:4).
