Thayer's Greek Lexicon
STRONGS NT 2503: ἰῶτα

ἰῶτα, τό, iota (A. V. jot), the Hebrew letter, yodh י, the smallest of them all; hence equivalent to the minutest part: Matthew 5:18. (Cf. Iota.)

Topical Lexicon
Meaning and Background

The term designates the smallest written symbol of the Greek alphabet and, by extension, the Hebrew yod, the tiniest consonant in the Torah. In everyday speech of the first century, the word evoked minuteness and precision, a nuance that made it an apt metaphor for exactness in Scripture.

Biblical Occurrence

Matthew 5:18 contains the sole New Testament instance: “For truly I tell you, until heaven and earth pass away, not a single jot, not a stroke of a pen, will disappear from the Law until everything is accomplished”. The phrase “single jot” renders the word, pairing it with “stroke of a pen” to highlight both letters and the tiniest scribal flourishes.

Theological Significance

1. Enduring Authority of the Law

Christ affirms the continuing validity of every detail of God’s revelation. No command, prophecy, or promise is irrelevant or expendable; the covenantal storyline remains intact until fully realized in Him.
2. Reliability of Scripture

By stressing even the smallest character, Jesus upholds verbal inspiration. Divine truth reaches down to the precise letters, undercutting any notion that the biblical text is merely approximate or conceptually inspired.
3. Christ’s Fulfillment Mission

The statement sets the tenor for the Sermon on the Mount. Jesus is not abolishing but fulfilling; His teaching intensifies rather than relaxes the moral and prophetic thrust of the Old Testament.

Historical Usage in Jewish and Greco-Roman Contexts

Yod, the Hebrew counterpart, frequently functioned as an abbreviation marker in scrolls and inscriptions. Mishnah tractates preserve rabbinic discussions about the proper formation of each letter, underscoring a shared reverence for textual accuracy. In Greek culture, iota could also symbolize insignificance (“not worth an iota”), revealing how Jesus appropriated a common idiom to make an authoritative claim.

Early Christian Reception

Church fathers such as Irenaeus and Jerome cited Matthew 5:18 to defend the unity of the Testaments and to confront Marcionite or Gnostic attempts to diminish Old Testament authority. The verse was also pivotal in medieval debates over vowel pointing and later in Reformation arguments for plenary inspiration.

Application for Teaching and Preaching

• Encourage confidence in the infallibility of Scripture; every promise stands.
• Motivate meticulous hermeneutics—context, grammar, and even verb tenses matter.
• Reinforce ethical obedience: if the smallest statute endures, discipleship must aim at wholehearted conformity.
• Highlight Christ’s perfect obedience, assuring believers that His fulfillment secures righteousness for all who trust in Him.

Implications for Christian Discipleship

Attention to “iotas” cultivates a heart that treasures God’s Word. When believers honor the text in its entirety, they mirror the attitude of the Savior who esteemed each letter. Such reverence manifests in careful study, humble submission, and eager proclamation of the gospel “once for all entrusted to the saints” (Jude 3).

Summary

Though appearing only once, the term serves as a linchpin for doctrines of inspiration, canon, and covenant continuity. It reminds the church that God’s redemptive plan is recorded with deliberate precision and will unfailingly reach consummation “until everything is accomplished.”
