περιτομῆς; (peritomes) in Romans 3:1: Noun Genitive Singular Feminine

Noun: the word names a reality or practice here, namely circumcision, and it functions as a substantive in the clause.

Genitive: the form usually marks a relationship to another noun, here pointing to what the usefulness is associated with or about.

Singular: the form is grammatically singular in this occurrence and refers to circumcision as one category or practice.

Feminine: the noun belongs to the feminine grammatical class, which is a language feature and does not by itself make a theological or biological claim.

τῆς ὠφελείας

The genitive is governed by the noun ὠφέλεια and depends on it in the question about advantage or profit.

It likely expresses the thing whose benefit is being asked about, so the phrase means the usefulness belonging to or arising from circumcision.

It does not by itself identify a subject, and it does not change the lemma into another word or force a full theological conclusion.

High: The genitive circumcision noun frames Paul's question about the advantage connected with circumcision.

Genitive noun qualifying ὠφελείας. marks circumcision as the thing whose benefit is being asked about. Attached to τῆς ὠφελείας τῆς περιτομῆς. Governed by the advantage or benefit question. The genitive states relation in the question, not the answer to Paul's argument.

What benefit is Paul asking about? He asks about the benefit or advantage connected with circumcision.

Direct: The form directly supports wording such as benefit of circumcision.

The genitive may be rendered of or connected with, but Paul's following argument answers the theological question. Feminine noun class does not add a gendered theological meaning.

Genitive question supplies the answer: The form frames what is being asked; the following verses provide Paul's answer.

The witness reads περιτομῆς in Romans 3:1 within the question, ἡ ὠφέλεια τῆς περιτομῆς;

The lemma περιτομή means circumcision, referring to the rite, the state of being circumcised, or the people marked by it depending on context.

Here the genitive works with ὠφέλεια to ask about circumcision's usefulness, so grammar points to relationship and reference rather than to a separate action or event.

Paul is asking what advantage remains in circumcision, continuing the discussion of Jewish privilege and its value before God.

In the broader canon, circumcision can mark covenant identity, but this verse asks about its practical benefit in the argument, not about creating righteousness on its own.

For readers and translators, the genitive should be heard as descriptive of the advantage in view, helping the question sound like 'What is the benefit of circumcision?'

Do not infer that the case alone proves covenant status, moral worth, or gendered meaning, and do not treat the grammar as overriding the argument of the verse.
