New American Standard Bible (NASB)
Psalm 50
18 "When you see a thief, you are pleased with him, And you associate with adulterers.
19 "You let your mouth loose in evil And your tongue frames deceit.
20 "You sit and speak against your brother; You slander your own mother’s son.
21 "These things you have done and I kept silence; You thought that I was just like you; I will reprove you and state the case in order before your eyes.
22 "Now consider this, you who forget God, Or I will tear you in pieces, and there will be none to deliver.
23 "He who offers a sacrifice of thanksgiving honors Me; And to him who orders his way aright I shall show the salvation of God."
Psalm 51
1 Be gracious to me, O God, according to Your lovingkindness; According to the greatness of Your compassion blot out my transgressions.
2 Wash me thoroughly from my iniquity And cleanse me from my sin.
3 For I know my transgressions, And my sin is ever before me.
4 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.
5 Behold, I was brought forth in iniquity, And in sin my mother conceived me.
