### Biblical Occurrences & Contextual Analysis
In biblical usage, `{{H2151}}` captures two distinct ideas.

This usage conveys a sense of quaking or shaking before divine power. Second, and more frequently, it denotes moral worthlessness and lack of self-control. It is used to label a person as "vile" ([[Jeremiah 15:19]], [[Lamentations 1:11]]) or a "glutton" ([[Proverbs 23:21]], [[Deuteronomy 21:20]]). It also describes behavior, such as being among "riotous eaters" [[Proverbs 23:20]] or a companion of "riotous men" [[Proverbs 28:7]].
### Related Words & Concepts
Several related words help define the context of moral looseness associated with `{{H2151}}`:
* `{{H5433}}` **çâbâʼ** (to quaff to satiety, i.e. become tipsy): This word for a drunkard or wine-bibber is frequently paired with `{{H2151}}`. In [[Deuteronomy 21:20]], a rebellious son is described as a "glutton, and a drunkard," and [[Proverbs 23:21]] warns that "the drunkard and the glutton shall come to poverty."
* `{{H1320}}` **bâsâr** (flesh; by extension, body, person): The object of gluttonous behavior is specified in [[Proverbs 23:20]], which warns against being among "riotous eaters of flesh."
* `{{H3196}}` **yayin** (wine (as fermented); by implication, intoxication): The warning in [[Proverbs 23:20]] places "winebibbers" alongside riotous eaters, linking the consumption of wine with the behavior described by `{{H2151}}`.
* `{{H400}}` **ʼôkel** (food): In a state of desperation, the people of Jerusalem give their treasures for "meat" to survive, a situation that leads to the declaration, "I am become vile" [[Lamentations 1:11]].
### Theological Significance
The theological and moral weight of `{{H2151}}` is significant, highlighting key principles of wisdom and divine judgment.
* **Moral Distinction:** The word establishes a clear contrast between good and evil. The LORD instructs Jeremiah to "take forth the precious from the vile," showing a separation between what is divinely valued and what is worthless [[Jeremiah 15:19]].
* **Consequences of Indulgence:** The wisdom literature uses `{{H2151}}` to warn against a lack of discipline. Being a "glutton" leads to poverty [[Proverbs 23:21]], and associating with "riotous men" brings shame to one's father [[Proverbs 28:7]]. This connects uncontrolled appetite directly to social and economic ruin.
* **The Power of God's Presence:** In contrast to human weakness, the word is used to describe the immense power of God, before whom even mountains "flowed down" [[Isaiah 64:3]]. The same root that signifies human worthlessness also depicts the awesome, humbling effect of God's appearance.
### Summary
In summary, `{{H2151}}` is a dynamic word that encompasses both profound physical force and deep moral failing. It serves as a label for those who are gluttonous and undisciplined, leading a life considered vile or worthless, and stands as a stark warning in wisdom texts. Simultaneously, it is used to paint a picture of God’s awesome power, capable of making the very mountains quake. This single term bridges the gap between the consequences of human prodigality and the overwhelming power of the divine.
