Mazmur 51:5

51:5 Look, I was guilty of sin from birth,

a sinner the moment my mother conceived me. ¹ 

Mazmur 90:5

90:5 You bring their lives to an end and they “fall asleep.” ² 

In the morning they are like the grass that sprouts up;

[51:5]  ¹ 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.

[90:5]  ² tn Heb “you bring them to an end [with] sleep.” The Hebrew verb זָרַם (zaram) has traditionally been taken to mean “flood” or “overwhelm” (note the Polel form of a root זרם in Ps 77:17, where the verb is used of the clouds pouring down rain). However, the verb form here is Qal, not Polel, and is better understood as a homonym meaning “to make an end [of life].” The term שֵׁנָה (shenah, “sleep”) can be taken as an adverbial accusative; it is a euphemism here for death (see Ps 76:5-6).
