Psalm 51, a prayer of repentance, was written by David when he was confronted by Nathan the prophet about his adultery with Bathsheba and his arranging the death of her husband Uriah (see 2 Sam 12).
In a sermon at Church of the Messiah on July 25, 2026, Kyle Kettering discussed two questions raised by Psalm 51:3-5, where David acknowledges the fact that he has sinned greatly and has no excuse.
The first question is from verse 4, where David confesses, "Against you, you only, have I sinned, and done what is evil in your sight." What does David mean here? Surely David also sinned against Bathsheba and Uriah. There are a number of scriptures that speak of someone sinning against another person, including:
- Genesis 42:22, which speaks of Joseph's brothers sinning against him;
- 1 Samuel 2:25, which contrasts sinning against a man and sinning against God;
- Luke 15:21, where the prodigal son acknowledges sinning against both God and his father.
A second, harder question is raised by verse 5. In the ESV, this verse says, "Behold, I was brought forth in iniquity, and in sin did my mother conceive me." This verse is often cited as a proof text for the Christian doctrine of original sin. Kyle observed, however, that it is not necessarily a good idea to make a poetic text like a psalm carry a lot of weight in a theology debate. (The key text on original sin is Romans 5, which is part of a theological discourse.)
Kyle went on to explain that there are other possible translations of verse 5. One issue is the translation of chet, the Hebrew word for "sin" in this verse. This is a word that usually means sin or impurity but can sometimes mean purity or cleanness. A discussion of Jewish sages on this point is recorded in the Talmud in Niddah 31b, where a couple of examples are cited. One is in Numbers 14:52, which is about the cleansing of a moldy house. The other is Psalm 51:7 ("Purge me with hyssop ..."), just a couple of verses after the one in question.
With this information in mind, it follows that another possible translation of verse 5 could be, "Behold, I struggled with iniquity, but in purity my mother conceived me." This translation has David taking full responsibility for what he has done---rather than saying original sin made him do it---which is consistent with the thrust of the psalm.
A lesson here, Kyle said, is that we should approach the biblical text with caution and humility to ensure, as much as possible, that we do not misrepresent it.
