### Core Meaning & Semantic Range

The term's meaning is derived from the concept of ferment and is central to understanding key biblical regulations, particularly concerning festivals and sacrifices.
### Biblical Occurrences & Contextual Analysis
In scripture, `{{H2557}}` is primarily used within legal and ritual commands. Its most frequent context is the prohibition against its consumption during the seven days of the Passover feast, a command tied to remembering the Exodus from Egypt ([[Exodus 13:3]], [[Deuteronomy 16:3]]). The penalty for eating **leavened bread** during this time was severe: to be "cut off from Israel" [[Exodus 12:15]]. Similarly, it was forbidden in sacrifices involving blood ([[Exodus 23:18]], [[Exodus 34:25]]) and most meat offerings made by fire ([[Leviticus 2:11]], [[Leviticus 6:17]]). However, its use was explicitly commanded in specific offerings, such as the two wave loaves of the firstfruits [[Leviticus 23:17]] and with the sacrifice of thanksgiving [[Leviticus 7:13]].
### Related Words & Concepts
Several related words clarify the regulations surrounding fermented foods:
* `{{H4682}}` **matstsâh** (unleaved bread, cake): This word is the direct counterpart to `châmêts`, referring to bread made without a leavening agent. It is often commanded to be eaten when **leavened bread** is forbidden, such as during the seven days of the Passover feast [[Deuteronomy 16:3]].
* `{{H7603}}` **sᵉʼôr** (leaven): This term refers to the leavening agent itself, the "barm or yeast-cake" that causes bread to become **leavened**. The Bible often prohibits both **leavened bread** `{{H2557}}` and the leavening agent **sᵉʼôr** `{{H7603}}` from being seen or found in Israelite homes during the Passover week [[Exodus 13:7]].
### Theological Significance
The theological significance of `{{H2557}}` is seen in its prescribed use in Israel's worship and remembrance.
* **Prohibition in Offerings:** The general exclusion of **leaven** from offerings made by fire unto the LORD indicates a standard for what is brought before Him [[Leviticus 2:11]]. An offering baken without **leaven** is described as "most holy" [[Leviticus 6:17]].
* **Remembrance of Redemption:** The strict prohibition of **leavened bread** during Passover served as a physical reminder of the haste with which the Israelites left Egypt [[Deuteronomy 16:3]]. Abstaining from it was an act of remembering their deliverance from the house of bondage [[Exodus 13:3]].
* **Prescribed Sacrificial Use:** In contrast to the general prohibition, **leavened** bread was required for the wave loaves of the firstfruits [[Leviticus 23:17]] and for offerings of thanksgiving [[Leviticus 7:13]]. The prophet Amos also mentions offering a sacrifice of thanksgiving with **leaven** [[Amos 4:5]].
### Summary
In summary, `{{H2557}}` is more than just a type of bread; it is a key element in biblical ritual law. Its meaning is highly contextual, most often representing what is forbidden during the sacred time of Passover and in most sacrifices presented to God. Yet, its required inclusion in certain offerings, like those for firstfruits and thanksgiving, demonstrates that its significance is defined by divine command. This term illustrates the detailed nature of the laws governing Israel's worship and remembrance.
