### Core Meaning & Semantic Range
The Hebrew word **ʼâyôm**, represented by `{{H366}}`, is defined as **frightful; terrible**. It derives from an unused root that means "to frighten." Despite its powerful meaning, it is a rare term, appearing only **3 times** across **3 unique verses** in the Bible, giving each instance significant weight.
### Biblical Occurrences & Contextual Analysis
The use of `{{H366}}` presents a striking contrast in scripture. In the Song of Solomon, it describes the overwhelming beauty of the beloved. She is called "beautiful" and "comely," but also "terrible as an army with banners" [[Song of Solomon 6:4]]. This imagery is repeated, where her appearance is compared to the morning, the moon, and the sun, yet she is also "terrible as an army with banners" [[Song of Solomon 6:10]]. In Habakkuk, the word shifts to a more conventional sense of dread. It describes a people who are both "terrible and dreadful," a force whose "judgment and their dignity shall proceed of themselves" [[Habakkuk 1:7]].
### Related Words & Concepts
Several related words help clarify the dual nature of being terrible or frightful:
* `{{H3372}}` **yârêʼ** (dreadful): This word, meaning to fear or revere, is paired directly with `{{H366}}` to describe a fearsome people, emphasizing their intimidating and frightening nature [[Habakkuk 1:7]].
* `{{H1713}}` **dâgal** (banners): Used to describe an army with banners, this term means to be conspicuous or raise a flag. It qualifies the "terrible" nature in Song of Solomon, suggesting an awe-inspiring, organized, and unignorable presence ([[Song of Solomon 6:4]], [[Song of Solomon 6:10]]).
* `{{H3303}}` **yâpheh** (beautiful): This word for beauty is used alongside `{{H366}}` to describe the beloved, highlighting that the "terrible" quality is not one of ugliness but of overwhelming, awe-inspiring majesty [[Song of Solomon 6:4]].
* `{{H4941}}` **mishpâṭ** (judgment): In Habakkuk, the "terrible" people's judgment proceeds from themselves, linking the concept of being frightful to self-derived authority and sovereign power [[Habakkuk 1:7]].
### Theological Significance
The theological weight of `{{H366}}` is tied to its depiction of overwhelming power, whether for attraction or for dread.
* **Awe-Inspiring Majesty:** In Song of Solomon, "terrible" is used as a high compliment. It portrays a beauty so profound and powerful that it is as striking and commanding as a full army on display, evoking awe rather than fear ([[Song of Solomon 6:4]], [[Song of Solomon 6:10]]).
* **Fearsome Sovereignty:** In Habakkuk, the word describes a people who are frightening because they operate by their own authority. Their terror is rooted in their self-determined "judgment" and "dignity," making them an unpredictable and dreadful force [[Habakkuk 1:7]].
* **Conspicuous Power:** The recurring image "as an army with banners" `{{H1713}}` reveals that the quality of `{{H366}}` is a visible and conspicuous one. It is a power that cannot be ignored, whether it manifests as breathtaking beauty or as formidable might.
### Summary
In summary, `{{H366}}` is a focused term that conveys an overwhelming and frightful power. While used sparingly, its context determines its nuance. It can illustrate the awe-inspiring majesty of a beloved figure, whose beauty is as commanding as an army [[Song of Solomon 6:4]], or it can define the dreadful, self-governing might of a fearsome people [[Habakkuk 1:7]]. In both cases, **ʼâyôm** signifies a presence so potent that it is truly terrible to behold.
