6 Heb “know.”
7 Heb “and my sin [is] in front of me continually.”
8 Heb “only you,” as if the psalmist had sinned exclusively against God and no other. Since the Hebrew verb חָטָא (hata’, “to sin”) is used elsewhere of sinful acts against people (see 306 2.a) and David (the presumed author) certainly sinned when he murdered Uriah (2 Sam 12:9), it is likely that the psalmist is overstating the case to suggest that the attack on Uriah was ultimately an attack on God himself. To clarify the point of the hyperbole, the translation uses “especially,” rather than the potentially confusing “only.”
9 The Hebrew term לְמַעַן (léma’an) normally indicates purpose (“in order that”), but here it introduces a logical consequence of the preceding statement. (Taking the clause as indicating purpose here would yield a theologically preposterous idea—the psalmist purposely sinned so that God’s justice might be vindicated!) For other examples of לְמַעַן indicating result, see 2 Kgs 22:17; Jer 27:15; Amos 2:7, as well as §38.3.
10 Heb “when you speak.” In this context the psalmist refers to God’s word of condemnation against his sin delivered through Nathan (cf. 2 Sam 12:7–12).
11 Heb “when you judge.”
12 Heb “Look, in wrongdoing I was brought forth, and in sin my mother conceived me.” The prefixed verbal form in the second line is probably a preterite (without vav [ו] consecutive), stating a simple historical fact. The psalmist is not suggesting that he was conceived through an inappropriate sexual relationship (although the verse has sometimes been understood to mean that, or even that all sexual relationships are sinful). The psalmist’s point is that he has been a sinner from the very moment his personal existence began. By going back beyond the time of birth to the moment of conception, the psalmist makes his point more emphatically in the second line than in the first.

ESVEnglish Standard Version

For I know my transgressions,

and my sin is ever before me.

Behold, I was brought forth in iniquity,

and in sin did my mother conceive me.

sinful from the time my mother conceived me.

For I am conscious of my rebellion,

and my sin is always before me.

I was sinful when my mother conceived me.

For I recognize my rebellion;

it haunts me day and night.

yes, from the moment my mother conceived me.

so that you are correct when you speak,

you are blameless when you judge.

Behold, in iniquity I was born,

and in sin my mother conceived me.

For I acknowledge my transgressions:

And my sin is ever before me.

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.

Behold, I was shapen in iniquity;

And in sin did my mother conceive me.
