The Greek word onikós, represented by G3684, describes something belonging to a ass. It is used in scripture to signify an object so large that it must be turned by a donkey, specifically a millstone. It appears 2 times across 2 unique verses in the Bible. This specific adjective emphasizes the immense size and weight of the millstone being described.
In its biblical usage, G3684 appears in a stark warning from Jesus about the severe consequences of causing others to sin. Both occurrences describe a grim fate for anyone who causes one of the "little ones" who believe in Him to stumble. The image presented is of a massive millstone, an onikós millstone, being hanged about a person's neck before they are drowned in the sea (Matthew 18:6, Luke 17:2). The use of this specific term highlights the inescapable and terrible nature of the judgment for such an offense.
Several related words help frame the context of this severe warning:
- G3458 mýlos (a "mill", i.e. (by implication), a grinder (millstone)): This is the noun that G3684 modifies. The combination of the two words describes not just any millstone, but one of the largest and heaviest types, an "ass-turned millstone" Matthew 18:6.
- G4624 skandalízō (to entrap, i.e. trip up (figuratively, stumble (transitively) or entice to sin, apostasy or displeasure)): This is the action that provokes the warning. The dire punishment is reserved for one who would offend one of the "little ones" Luke 17:2.
- G5137 tráchēlos (the throat (neck), i.e. (figuratively) life): The millstone is to be hung about the neck of the offender, a detail which emphasizes the personal and fatal nature of the consequence Matthew 18:6.
- G2670 katapontízō (to plunge down, i.e. submerge): This verb depicts the ultimate outcome. Weighed down by the massive millstone, the person would be drowned in the sea Matthew 18:6.
The theological weight of G3684 is concentrated in its powerful imagery.
- Gravity of Sin: The use of G3684 to specify a donkey-driven millstone, an object of immense weight, serves as a hyperbole to illustrate the extreme seriousness of causing a believer to fall into sin.
- Value of the Faithful: The severity of the punishment directly reflects the high value God places on his "little ones." The choice of such a weighty and specific term underscores the protective watchcare over those who believe Matthew 18:6.
- Certainty of Judgment: Being cast into the sea with an onikós millstone is an image of certain and irreversible death. The word contributes to a sense of finality and the inescapable nature of judgment for those who harm the faithful Luke 17:2.
In summary, G3684 is more than a simple adjective. Though used only twice, onikós provides a crucial detail that intensifies one of Jesus' most sobering warnings. By specifying a millstone so large it required an animal to turn it, the word creates a powerful and unforgettable illustration of the gravity of sin and the profound value God places on each of his followers.
