who, which, what, that

Definition

ὅς is a relative pronoun meaning 'who,' 'which,' 'what,' or 'that.' It is used to introduce a clause that describes or provides more information about a person or thing mentioned earlier. For example, in Matthew 1:16, it refers to a person ('Joseph, the husband of Mary, of whom [ὅς] was born Jesus'), while in Matthew 1:23, it refers to a thing ('Behold, the virgin shall conceive and bear a son, and they shall call his name Immanuel,' which [ὅς] means, 'God with us'). It can also function as a general relative pronoun, equivalent to 'the one who' or 'that which,' as seen in contexts like Matthew 3:11 ('He who [ὅς] comes after me is mightier than I').

Biblical Usage

ὅς appears over 1,200 times in the New Testament, making it one of the most common words. It is used in every book and in a wide variety of contexts—narrative, discourse, and epistolary—to connect ideas and specify relationships. For instance, it often introduces explanatory clauses about Jesus' identity (Matthew 1:23) or describes the actions of key figures (Matthew 2:9, 'the star which [ὅς] they had seen'). In the Gospels and Acts, it frequently appears in historical narration, while in the Epistles, it is used for theological precision, such as defining Christ's role (e.g., 'who [ὅς] is the image of the invisible God' in Colossians 1:15).

Etymology

ὅς is a primitive Greek relative pronoun with no certain derivation from a simpler root. It is part of the core vocabulary of ancient Greek, related to forms like ἥ (hē, 'who' feminine) and ὅ (ho, 'which' neuter). Its function is analogous to relative pronouns in other Indo-European languages, serving as a fundamental grammatical tool for subordination and reference. The meaning has remained stable from classical through Koine Greek, consistently denoting relation to an antecedent.

Semantic Range

As a grammatical tool, ὅς itself is not theologically loaded, but its usage is crucial for precise biblical interpretation. It allows authors to make definitive statements about God, Christ, and salvation. For example, in Matthew 1:23, it links the prophecy to Jesus, affirming His identity as Immanuel. In passages like John 1:1 ('the Word was with God, and the Word was God'), relative clauses using forms of ὅς help define the nature of the Trinity and Christ's divinity. Understanding its function helps readers see how biblical arguments are constructed, clarifying connections between ideas and highlighting key theological claims. ὅστις (hostis, G3748) — a more indefinite relative pronoun meaning 'whoever' or 'whatever,' often used for general classes or indefinite references. ἥτις (hētis, G3748) — the feminine form of ὅστις, with similar indefinite force. ὅσπερ (hosper, G3739 & G4007) — an emphatic compound form meaning 'the very one who,' adding emphasis to the antecedent.
