1 tn 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 BDB 306 s.v. 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.”
2 tn The Hebrew term לְמַעַן (lÿma’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 IBHS 638-40 §38.3.
4 tn Heb “when you judge.”
5 tn 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.
