Hoti (ὅτι) — Meaning & Usage in the Bible
ὅτι (G3754) is a common Greek conjunction used either declaratively to introduce a statement ('that') or causatively to give a reason ('because, for').
Meaning of the word
ὅτι is a versatile conjunction that appears roughly 1,296 times in the Greek New Testament. In its declarative use it functions like English 'that,' introducing a content clause—what someone said, thought, saw, or knew. For instance, when Jesus says, 'Ye have heard that it was said…' (Matthew 5:21), ὅτι introduces the content of what was said by the ancients.
In its causative use, ὅτι means 'because' or 'for,' supplying the reason for the preceding statement. The Beatitudes in Matthew 5:3–10 illustrate this pattern clearly: 'Blessed are the poor in spirit: for (ὅτι) theirs is the kingdom of heaven.' Each blessing is followed by a ὅτι-clause that grounds the blessing in a divine promise.
Because the conjunction is grammatically versatile, the context—not the word itself—determines which sense is intended. In narrative and teaching sections, the same form can shift between explanation and quotation without any change in spelling.
Usage in Scripture
ὅτι is woven throughout the Gospels, Acts, Epistles, and Revelation. Matthew uses it heavily in the Sermon on the Mount to ground each beatitude with a divine reason (Matthew 5:3–12) and to frame Jesus' contrast with the old covenant teaching (Matthew 5:17, 20–21).
Beyond Matthew, ὅτι serves as a structural conjunction in theological discourse. It introduces explanations of doctrine ('we know that…'), quotations of Scripture or speech ('it is written that…'), and reasons for exhortation ('rejoice, for…'). Its frequency—155 occurrences across 134 verses—makes it one of the most recognizable particles in the Greek New Testament.
Translators handle ὅτι in various ways: as 'that,' 'because,' 'for,' or even implicitly. Readers should pay attention to the surrounding clause to identify which sense is in play.
The word in detail
- G3754 ὅτι (hoti) is a conjunction with two principal senses: (1) declarative—introducing a content clause, often translatable 'that' (e.g., Matthew 5:21: 'Ye have heard that it was said'); (2) causative—giving a reason, translatable 'because, for' (e.g., Matthew 5:3: 'Blessed are the poor in spirit: for theirs is the kingdom of heaven'). The context determines which sense applies, since the form is identical.
Example verses
- Matthew 5:3 Here ὅτι introduces the reason for the blessing: the poor in spirit are blessed because theirs is the kingdom of heaven. A clear example of the causative 'for/because' sense.
- Matthew 5:17 Jesus uses ὅτι declaratively: 'Think not that (ὅτι) I came to destroy the law…' The conjunction introduces the content of what the disciples should not think.
- Matthew 5:20 ὅτι introduces the reason Jesus gives for the warning: unless righteousness exceeds the scribes' and Pharisees', one will not enter the kingdom. Causative use.
- Matthew 5:21 ὅτι introduces the content of what was 'said to them of old time'—a declarative use introducing a quoted saying.
Common questions
Is ὅτι always translatable the same way?
No. Translators render it variously as 'that,' 'because,' 'for,' or even leave it implicit. The English rendering depends on whether the clause introduces a statement (declarative) or gives a reason (causative).
How can a reader tell whether ὅτι means 'that' or 'because'?
Look at the logic of the sentence. If ὅτι introduces what someone said, thought, or knew, it is declarative ('that'). If it explains why the previous statement is true, it is causative ('because, for'). The two can coexist; sometimes ὅτι simultaneously reports words and supplies a reason.
Why is ὅτι so frequent in the New Testament?
Because Greek lacks the range of separate conjunctions found in English for quoting speech and explaining reasons. ὅτι conveniently serves both functions, allowing authors to introduce content clauses and causal explanations with a single, versatile particle.
