Shared ground
Nehemiah frames what he is about to say as a serious appeal for God’s attention: “ear” and “eyes” picture careful notice and active listening, not a casual hearing. This request is joined to confession: he asks God to listen as he admits wrongdoing. (Explicit in the text.)
He presents himself as God’s servant and prays for “the children of Israel,” also called God’s servants. The confession is corporate (“we have sinned”) and personal (“I and my father’s house have sinned”). (Explicit in the text.)
He summarizes their wrong as both broad (“we acted very corruptly”) and specific (“we did not keep the commandments, statutes, and ordinances…commanded…through Moses”). Whatever the exact distinctions among those terms, the point is comprehensive failure to keep what God had instructed. (Explicit in the text; the “comprehensive” framing is a reasonable inference from the piled-up terms.)
Where interpretation differs (only where needed)
Two details are read with some variety.
First, “day and night” may be taken as either (a) nonstop praying without interruption, or (b) repeated, persistent prayer over time (regularly, continually). The sentence stresses sustained urgency either way.
Second, “my father’s house” may be read narrowly (his immediate household) or more broadly (his extended family line or clan). In both readings, Nehemiah refuses to speak as though the problem belongs only to “others.”
Why the disagreement exists
The phrases are idiomatic and elastic. “Day and night” is a common way to speak about perseverance, but it can also be heard literally. “Father’s house” can refer to different sizes of family grouping depending on context.
What this passage clearly contributes
These verses present confession as truthful and owned: the community’s sin is named as sin “against” God, and the leader includes himself in what is confessed. They also link Israel’s present distress to covenant unfaithfulness: failure to keep what was commanded through Moses is treated as the central description of their corruption. The passage therefore establishes the moral and covenantal dimension of the crisis before Nehemiah moves to his later appeal in Nehemiah 1:8–11.
